Answer:

1.) 2x²+2x-4

Distributive property

(2x - 2) (x + 2)

Correct answer: 2x^2 + 2x - 4

Factoring technique: FOIL METHOD

(8x + 1) (8x² - 8x - 2)

Correct answer: 8x^3-56x^2-24x-2

Factoring technique: Distribution and combine like terms

(x - 10) (x + 1)

Correct answer: x^2 -9x - 10

Factoring technique: FOIL METHOD

(x - 15) (x + 5)

Correct answer: x^2 - 10x - 75

Factoring technique: FOIL METHOD
