We learned to factor complex trinomials today (of the form where ). 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.
