Question

Use the product of sum and difference to find 32 × 28.

Hint:

The methods used to find the product of binomials are called special products.
Difference of squares is a case of a special product which occurs when we multiply a binomial by another binomial with the same terms but the opposite sign

The correct answer is: 896


    32 can be written as (30 + 2) and 28 can be written as (30 - 2)
    So, 32 × 28 can be written (30 + 2) ×  (30 - 2)
    (30 + 2) ×  (30 - 2)  = 30(30 - 2) + 2(30 - 2)

    =  30(30) + 30(-2) + 2(30) + 2(-2)

    = 900 - 60 + 60 - 4

    = 900 - 4

    = 896
    Final Answer:
    Hence, the simplified form of 32 × 28 is 896.
     

    This question can be easily solved by using the formula
    (a + b)(a - b) = a2 - b2

    What is the gradient of a line parallel to the line whose equation -2x + y = -7 is:

    Hint:
    The slope/ gradient of a line is the measure of steepness of a line. It is understood that the slope of all parallel lines in the xy plane are equal. So first, we find the slope from the given equation of a line by using the slope intercept form of a line which is y = mx + c, , where m is slope and c is the y intercept. This gradient will be equal to the gradient of any line parallel to it.
    Step by step solution:
    The given equation of the line is
    -2x + y = -7
    We convert this equation in the slope intercept form, which is
    y = mx + c
    Where m is the slope of the line and c is the y-intercept.
    We rewrite the equation -2x + y - 7, as below
    y = 2x - 7
    Comparing with y = mx + c, we get that m = 2
    Thus, the gradient of line -2x + y = 7 is m = 2.
    We know that the gradient of any two parallel lines in the xy plane is always equal.
    Hence, the gradient of a line parallel to the line whose equation -2x + y = -7 is m = 2.
    Note:
    We can find the slope and y-intercept directly from the general form of the equation too; slope =negative a over b  and y-intercept = c over b, where the general form of equation of a line is ax + by + c = 0. Using this method, be careful to check that the equation is in general form before applying the formula. Here, we have, a = -2, b = 1, so we get m equals negative fraction numerator negative 2 over denominator 1 end fraction equals 2

    Write equation of the line containing (-3, 4) and (-1, -2)

    Hint:
    We are given two points and we need to find the equation of the line passing through them. Recall that the equation of a line passing through two points (a, b) and (c, d) is given by
    Step by step solution:
    Let the given points be denoted by
    (a, b) = (-3, 4)
    (c, d) = (-1, -2)
    The equation of a line passing through two points (a, b) and (c, d) is
    fraction numerator y minus d over denominator d minus b end fraction equals fraction numerator x minus c over denominator c minus a end fraction
    Using the above points, we have
    fraction numerator y minus left parenthesis negative 2 right parenthesis over denominator negative 2 minus 4 end fraction equals fraction numerator x minus left parenthesis negative 1 right parenthesis over denominator negative 1 minus left parenthesis negative 3 right parenthesis end fraction
    Simplifying the above equation, we have
    fraction numerator y plus 2 over denominator negative 6 end fraction equals fraction numerator x plus 1 over denominator negative 1 plus 3 end fraction
    not stretchy rightwards double arrow fraction numerator y plus 2 over denominator negative 6 end fraction equals fraction numerator x plus 1 over denominator 2 end fraction
    Cross multiplying, we get
    2(y + 2) = -6(x + 1)
    Expanding the factors, we have
    2y + 4 = -6x - 6
    Taking all the terms in the left hand side, we have
    6x + 2y + 4 + 6 = 0
    Finally, the equation of the line is
    6x + 2y + 10 = 0
    Dividing the equation throughout by2, we get
    3x + y + 5 = 0
    This is the general form of the equation.
    This is also the required equation.
    Note:
    We can simplify the equation in any other way and we would still reach the same equation. The general form of an equation in two variables is given by ax + by + c = 0, where a, b, c are real numbers. The student is advised to remember all the different forms of a line, like, slope-intercept form, axis-intercept form, etc.

    Show m = 2 for the straight line 8x - 4y = 12.

    Hint:
    We need to verify the value of m for an equation of straight line. We take the help of slope intercept form of equation of a line and convert the given equation in the form y = mx + c. Then we compare both the equations to find the value of m and check if it is equal to the given value.
    Step by step solution:
    The slope/ gradient of a line is denoted by m.
    The given equation of the line is
    8x - 4y = 12
    We convert this equation in the slope intercept form, which is
    y = mx + c
    Where m is the slope of the line and c is the y-intercept.
    We rewrite the equation 8x - 4y = 12, as below
    -4y = -8x - 12
    Dividing the above equation by (-4) throughout, we get
    fraction numerator negative 4 over denominator negative 4 end fraction y equals fraction numerator negative 8 over denominator negative 4 end fraction x minus fraction numerator 12 over denominator negative 4 end fraction
    Simplifying, we have
    y = 2x + 3
    Comparing with y = mx + c, we get that m = 2
    Thus, m = 2 for the straight line 8x - 4y = 12
    Note:
    We can find the slope and y-intercept directly from the general form of the equation too; slope =negative straight a over straight b  and y-intercept = c over b, where the general form of equation of a line is ax + by + c = 0. Using this method, be careful to check that the equation is in general form before applying the formula. Here, we have, a = 8, b = -4, so we get m equals negative fraction numerator 8 over denominator negative 4 end fraction equals 2

    -4y = -8x - 12
    Dividing the above equation by (-4) throughout, we get
    fraction numerator negative 4 over denominator negative 4 end fraction y equals fraction numerator negative 8 over denominator negative 4 end fraction x minus fraction numerator 12 over denominator negative 4 end fraction
    Simplifying, we have
    y = 2x + 3
    Comparing with y = mx + c, we get that m = 2
    Thus, m = 2 for the straight line 8x - 4y = 12
    Note:
    We can find the slope and y-intercept directly from the general form of the equation too; slope =negative straight a over straight b  and y-intercept = c over b, where the general form of equation of a line is ax + by + c = 0. Using this method, be careful to check that the equation is in general form before applying the formula. Here, we have, a = 8, b = -4, so we get m equals negative fraction numerator 8 over denominator negative 4 end fraction equals 2

    Simplify. Write each answer in its standard form.
    left parenthesis negative 5 x minus 6 right parenthesis minus open parentheses 4 x squared plus 6 close parentheses

    Explanation:
    • We have been given a function in the question.
    • We will have to simplify it and further write the answer in its standard form.
    Step 1 of 1:
    We know that in polynomial we add/subtract like terms
    So,
    left parenthesis negative 5 x minus 6 right parenthesis minus open parentheses 4 x squared plus 6 close parentheses
    negative 4 x squared minus 5 x minus 12
    Now, We know that the terms are written in descending order of their degree.
    So, In the standard form
    The given polynomial will be negative 4 x squared minus 5 x minus 12.

    Simplify -6 + 4a2 + 2b2 - 7xz - 3xz + 4a2 - 5b2 - 2.

    Answer:
    • Hint:
    ○        Group the like terms.
    ○        Like terms are those whose coefficients are the same.
    ○        Perform basic arithmetic operations on like terms.
    • Step by step explanation:
    ○        Given:
    Expression: -6 + 4a2 + 2b2 - 7xz - 3xz + 4a2 - 5b2 - 2.
    ○        Step 1:
    ○        Group like terms.
    rightwards double arrow-6 + 4a2 + 2b2 - 7xz - 3xz + 4a2 - 5b2 - 2
    rightwards double arrow( -6 - 2) + (4a2 + 4a2) - (7xz + 3xz) + (2b2 - 5b2 )
    rightwards double arrow( -8) + (8a2) - (10xz ) + (- 3b2 )
    rightwards double arrow 8a2 - 3b2 - 10xz - 8
    • Final Answer:
    Hence, the other term is 8a2 - 3b2 - 10xz - 8.
