## Factoring ax 2 + bx + c where a ≠ 1

So far, we have restricted our trinomial factoring to trinomials like :

x2 -x-6
where the leading coefficient = 1

## Factoring ax2 + bx + c where a ≠ 1

Let's multiply two binomials to get a trinomial whose leading
coefficient is not equal to 1:

Note: when the leading coefficient ≠ 1,
the middle coefficient is not the sum
of the last two terms !
