Question

Which expression is the factored form of x2 – 7x + 10? (x + 3)(x + 4) (x – 3)(x – 4) (x – 2)(x – 5) (x + 2)(x + 5)

Answer 1

(x-2)(x-5) because -5x-2=10 and -5+-2=-7

Answer 2

In order to solve this, we can multiply out the answer choices and check if they are correct by using FOIL. A would be x^2 + 7x + 12. B would be x^2 - 7x + 12. C would be x^2 - 7x + 10. D would be x^2 + 7x + 10. The answer choice that matches the question is C. (x - 2)(x - 5).

Hope this helps!
