Name the binomial you can multiply by (x 9) to get the product x^2 5x - 36.

a. 4 - x

b. x 6

c. x - 4

d. x - 6

If you would like to solve (x^2 + 5x - 36) / (x + 9), you can do this using the following steps:

a = ?

(x + 9) * (x + a) = (x^2 + 5x - 36)

x^2 + ax + 9x + 9a = x^2 + 5x - 36

ax + 9x = 5x

a + 9 = 5

a = 5 - 9

a = - 4

The correct result would be c. x - 4.
