@RossB97 You can also watch the quadratic formula video (near the end I believe) and I walk through the concept.

@RossB97 You're welcome. About the b^2 - 4ac. It's called the discriminant (D) and it's a part of the quadratic formula -b/2a +/- root(b^2-4ac)/2a. The biggest thing to realize is that it's under a root and after the plus/minus. 3 possibilities: D can be positive (meaning +/- root of positive giving 2 answers), D can be 0 (meaning +/- root 0 or nothing being added and subtracted and leaving 1 answer), or D can be negative (meaning +/- root of negative giving 2 imaginary (0 real).
