Best ResponseYou've already chosen the best response.0Theres two formulas you must know in dealing with parabolics. 1. finding the solutions to the number of real solutions in a quadratic, the discriminant: \(b^24ac\) 2. the vertex of a parabola will always be solved for x, unless the parabola is turned in a different direction. this is represented by: \(x= \dfrac{b}{2a}\)

Best ResponseYou've already chosen the best response.0Correction: #1 does not just reference real solutions, but it also tells you possible imaginary solutions as well.
