Solving Quadratic Equations by Factoring - YourTeacher.com

For a complete lesson on solving quadratic equations by factoring, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to solve quadratic equations by the method of their choice, using the following rules. If possible, use the factoring method. If there is no coefficient on the squared term, and the middle term of the trinomial is even, use completing the square. If there is a coefficient on the squared term, and/or if the middle term is odd, use the quadratic formula. If the variable only appears in the squared term, get the variable by itself on one side of the equation and square root both sides.

I love how my google searches weeks before exam week are things like "French Imperative tense rules" and "converging lenses", and now that exam week's come around they're more like "Haitian Voodoo luck symbols".
