One of the things I've struggled with most in algebra/calculus is all the "factoring tricks". When I take time away from doing math I inevitably forget most if not all of them. The old proverb "use it or lose it" definitely comes into play.
I'm a huge fan of Khan Academy and have started to keep a list of tutorials which demonstrate factoring, but I haven't found them all:
- Factoring and the Distributive Property (3 lessons)
- Solving a quadratic by factoring
- Factoring Trinomials by Grouping (6 lessons)
- Solving Quadratic Equations by Factoring (3 lessons)
- Factoring Special Products (3 lessons)
- Completing the Square
- Factoring perfect square trinomials
Was wondering if anyone could help me fill in the gaps by providing their own list of factoring tips be them in the thread itself, or to online resources like Khan Academy, this site, or elsewhere
