Solving ax^2 + bx + c
 

I can not remember how and my school took away my reference material http://www.discussworldissues.com/fo...lies/frown.png can someone help me remember? *I do not search anymore because the last time I did I got some weird sites*

Using the Quadratic Formula lets you solve Quadratic Equations.

You need more than one equation to solve it. At least 1 more, but up to about 3 or 4 I believe. Since if you substitute away equations you can solve for different variables.

Oh. I misunderstood the question.

You're talking about the standard form quadratic equation.

QQ I hate factoring..

You can use either. If you have integer roots, factorisation is much quicker and cleaner. Otherwise, quadratic's the way to go.
