When you use the quadratic equation formula to solve a quadratic equation, YOU WILL ALWAYS get 2 ANSWERS,

unless the DISCRIMINANT: b%5E2+-+4ac has a value that's equal to 0 (zero). You should realize that with the "±"

being part of the quadratic equation, you will, MOST TIMES, obtain 2 values for the variable in the equation.
