Quadratic formula - Wikipedia

WebA quadratic function is a polynomial function of degree two. The graph of a quadratic function is a parabola. The general form of a quadratic function is f(x) = ax2 + bx + c where a, b, and c are real numbers and a ≠ 0. The standard form of a quadratic function is f(x) = a(x − h)2 + k where a ≠ 0. WebSolving General Quadratic Equations by Completing the Square. We can complete the square to solve a Quadratic Equation (find where it is equal to zero). But a general Quadratic Equation can have a coefficient of a in front of x 2: ax 2 + bx + c = 0.
