Answer:

(X - 9) is one factor

(X + 4) is the other factor

Step-by-step explanation:

You can factor polynomials with guess work or with polynomial division

To factor using guess work search for a number that will multiply with -9 to equal -36 and add with -9 to equal -5.

In order for -9 to add with another number and equal -5 you need to add 4 to it. And because -9 will multiply with 4 to equal -36 as well, 4 is confirmed to be the other factor. You can write out the factor as (x + 4)

What is this factored?

Mandarinka [93]

The factored form of an equation is the simplest form of the equation that is obtained by factoring out a common variable or constant from multiple terms. Many types of polynomials are presentable in factored form, but the more terms an equation contains, the more difficult it is to find common factors.
