Question

Find the product.Β (2π‘₯ βˆ’ 4)(2π‘₯ + 4)

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: 16


    (2π‘₯ βˆ’ 4)(2π‘₯ + 4) = 2π‘₯(2π‘₯ + 4) βˆ’ 4(2π‘₯ + 4)

    =Β  2π‘₯(2π‘₯) + 2π‘₯(4) - 4(2π‘₯) - 4(4)

    = 4π‘₯2 + 8π‘₯ - 8π‘₯ - 16

    = 4π‘₯2 - 16
    Final Answer:
    Hence, the simplified form of (2π‘₯ βˆ’ 4)(2π‘₯ + 4) is 4π‘₯2 - 16
    Β 

    This question can be easily solved by using the formula
    (a + b)(a - b) = a2Β - b2
