Hey,

I have some general questions from "all-around" math:

- When factoring, why do you have to use perfect squares?
- Is the equation ax^2+bx+c=0 the same as the equation y=ax^2+bx+c? (referring to quadratics)
- What does the term "difference of squares" imply?
- Are there any general rules when factoring trinomials?

Thanks everyone.
