X2 + 5x - 50 A) (x + 25) (x - 2) B) (x - 5) (x + 10) C) (x - 10) (x + 5) D) (x + 2) (x - 25)

The correct answer is B) (x - 5) (x + 10)

Step-by-step explanation:

The constants at the end of the parenthesis need to add to the middle term

10 + - 5 = 5

And they need to multiply to the end term

-5 * 10 = - 50

This makes it the correct choice.
