The PQ formula is used to solve quadratic equations. The easiest way to solve ax² bx c = 0 for the value of x is to factor the square factor, set each factor equal to zero and then solve.
Sometimes the square is too messy, or it doesn't matter, or you just don't feel like factoring. While factoring can't always be successful, the quadratic formula can always find the solution.
The quadratic formula uses "a", "b" and "c" of "ax2 bx c", where "a", "b" and "c" are just numbers
