Answer 2

x² - x - 12 = (x - 4)(x - 3)

Explanation:

We have the trinomial x² - x - 12.

We have to show two binomials to be factors of this above trinomial.

For this first we have to factorize the trinomial.

Now, x² - x - 12

= x² - 4x + 3x - 12

= x(x - 4) + 3(x - 4)

= (x - 4)(x - 3)

So the binomials are (x - 4) and (x - 3) that are factors of the trinomial x² - x - 12. (Answer)
