What are the steps to solving a quadratic equation?

Quadratic Equation solution for f(x) or y = ax² +bx + c is:
x = -b/2a +-√(b² -4ac)/2a (Vertex ± offsets)
This ALWAYS works
There are so far 8 common methods to solve quadratic equations, They are: graphing, completing the squares, quadratic formula, factoring FOIL, The Diagonal Sum Method, the Bluma Method, the popular factoring AC Method, and the new Transforming Method.

Depends on what works best.
Some can be factored -- then each binomial factor can be set equal to 0 and solved for solutions.
or -- Compete the square -- then take the sq root -- then solve for x
or -- use the quadratic formula
or -- graph the equation and find the values where it crosses the x axis.
Those are 4 ways to solve a quadratic.

There at least four ways: complete the square, factor into two binomials (FOIL), quadratic formula, or graphing.
