Multiply both sides by 2a to clear the fraction Add b to both sides to isolate the radical term Square both sides to eliminate the radical Add -b² to both sides Divide through by -4a Simplify Add -c to both sides to get 0 on the right Multiply through by -1 to minimize negative and minus signs: which is the general quadratic equation, which is what we always start with to derive the quadratic formula.

"Find online" is not necessary and not useful. The solution formula is shown derived in intermediate algebra books.

You just need to be able to start with equation in the form of ax^2+bx+c=0, and to find c, c=-ax^2-bx
