Quadratic Formula : Solving a Quadratic ( x^2) Finding the X's Type in your numbers and find the Zeros to your Parabola! Example: 2x^2-3x-15=-4x add 4x to both sides 2x^2+1x-15=0 a=2 b=1 c=-15 Plug it in -b+-sqrt(b)^2-4ac/2a -1+-sqrt(1)^2-4(2)(-15)/2(2) simplify -1+-sqrt121/4 square root -1+-11/4 solve -1+11/4 = 2.5 -1-11/4 = -3 X = {5/2 , -3}
