Question

. Factor. x2 + 2x − 35 (x + 7)(x − 5) (x − 7)(x + 5) (x + 7)(x + 5) (x − 7)(x − 5)

Answer 1

Explanation:

(x+7)(x-5)

You need to find two numbers that multiply to make -35, but summed together make +2. Thus +7 and -5 are your only options here.

Answer 2

(x-5) (x+7)

Explanation:

x^2 + 2x − 35

What two numbers multiply to -35 and add to 2

-5 *7 = -35

-5+7 =2

(x-5) (x+7)
