While Mia's answer is not shown, the correct process is:
This trinomial is in the form ax²+bx+c. In this case, x=1. We want factors of c (in our trinomial, -12) that sum to b (in our trinomial, 4).
To make -12, we can multiply:
1(-12)
-1(12)
2(-6)
-2(6)
3(-4)
-3(4)
The correct set of factors are the ones that sum to positive 4. The only ones that do this are -2 and 6. These are the roots, so factored form is:
(x-2)(x+6).
