Question

Ifx- 9 is a factor of x2 – 5x – 36, what is the other factor?

Answer 1

Hey there! :)

Answer:

(x + 4).

Step-by-step explanation:

When finding the factors of a polynomial with a leading coefficient of 1, we must look for numbers that sum up to -5 and multiply into -36.

We are already given -9 as one of the numbers, so simply divide from -36 to solve for the remaining number.

-36 / (-9) = 4.

Therefore, this equation in factored form would be:

(x - 9) (x + 4)

The other factor being (x + 4).

Answer 2

(X+4) is the answer to this
