Question

Which of the binomials below is a factor of this trinomial x^2+x-12

Answer 1

x+4

Explanation:

This is the answer for the A P E X test.

Answer 2

`x^2+x-12`

Factor:

`\left(x-3\right)\left(x+4\right)`

Factoring: Finding what to multiply together to get an expression.

• Make two sets of parentheses. Put
  `x` on in each of them: (x )(x )
• Because there is a negative sign in front of the 12, you would need to put a plus sign and a negative sign in each parentheses: (x- )(x+ )
• 3*4=12 :
  `\left(x-3\right)\left(x+4\right)`

Hope this helps!!!
