Question

# Find the product. (𝑥 + 9)(𝑥 + 9)

Hint:

### The methods used to find the product of binomials are called special products.

Multiplying a number by itself is often called squaring.

For example (*x* + 3)(*x* + 3) = (*x* + 3)2

## The correct answer is: 81

### (x + 9)(x + 9) = x(x + 9) + 9(x + 9)

= x(x) + x(9) + 9(x) + 9(9)

= x^{2} + 9x + 9x + 81

= x^{2} + 18x + 81

Final Answer:

Hence, the simplified form of (𝑥 + 9)(𝑥 + 9) is x^{2} + 18x + 81

^{2}+ 9x + 9x + 81

^{2}+ 18x + 81

Final Answer:

Hence, the simplified form of (𝑥 + 9)(𝑥 + 9) is x

^{2}+ 18x + 81

This question can be easily solved by using the formula

(a + b)2 = a2 + 2ab + b2

### Graph the equation

We can find the tabular values for any points of x and then plot them on the graph. But we usually choose values for which calculating y is easier. This makes plotting the graph simpler. We can also find the values by putting different values of y in the equation to get different values for x. Either way, we need points satisfying the equation to plot its graph.
