Question

Which of the binomials below is a factor of this trinomial?
x² + 3x - 4

Answer 1

(x+4) or (x-1)

Explanation:

Do this by factoring out your equation. To do this, think about which two numbers multiply to be -4 but also add up to be 3 (the -4 came from multiplying the first value (the 1 that is attached to the
`x^(2)`) and the last value, which is -4. The 3 came from the middle term).

The two numbers you should have gotten are 4 and -1. Therefore, (x+4) and (x-1) are both of the binomials that could be your answer
