Question

Factor:

7x^3−14x^2+5x−10

A. (7x^2+5)(x−2)

B. 7x^2(x−2)+5(x−2)

C. Can't Factor

Answer 1

It's A.

Answer 2

clearly, it's A, but these kids can't do math

Answer 3

you have to factor out 7x^2 from 7x^3 - 14x^2 and that becomes 7x^2(x - 2)

then factor out 5 from 5x-10 and you get 5(x - 2)

7x^2(x - 2) + 5(x - 2)

(x - 2)(7x^2 + 5)
