Answer 1

(x-5) (x+4)

Explanation:

x^2 - X-20

Factor

What two numbers multiply to -20 and add to -1

-5*4 = -20

-5+4 = -1

(x-5) (x+4)

Answer 2

Hey there! :)

Answer:

A. x - 5

B. x + 4

Explanation:

Starting with:

x² - x - 20

Find two numbers that add up to -1 and multiply to form -20. We get:

-5, and 4. Use these numbers when writing this equation in factored form:

(x - 5) (x + 4) is the trinomial in factored form. The two binomials that are factors are:

A. x - 5

B. x + 4.
