Hi there!

the simplest way to solve " ax ² + bx + c = 0" for the value of x is to factor the quadratic, set each factor equal to zero, and then solve each factor. The Quadratic Formula uses the " a ", " b ", and " c " from " ax ² + bx + c ", where " a ", " b ", and " c " are the "numerical coefficients" of the quadratic equation.
