Question

Select the two binomials that are factors of this trinomial.

Answer 1

for $x^2-x-30$

find what 2 numbers multiply to get -30 and add to get -1

-6 and 5

factors to (x-6)(x+5)

so answers are A and C

Answer 2

Answer: A & C

Step-by-step explanation:

x² - x - 30

            ∧

          1  -30 = -29

          2  -15 = -13

          3   -10 = -7

          5    -6 = -1     This is equal to the b-value of -1 so THIS WORKS!

(x + 5) (x - 6)
