# MPM2D Factoring Complex Trinomials – 2015-12-04

We learned to factor complex trinomials today (of the form $ax^2+bx+c$ where $a \neq 1$). It’s more challenging than factoring simple trinomials (hence the name!).

Important tip: always look to see if there is a common factor that you can remove first. If there is, you can factor it out and have a simpler expression to work with.

Here are the practice questions:

And here’s a video that explains how to factor this kind of trinomial. It’s a little lengthy, and I go into a long explanation of why it works, but it’s all there.
