How to complete the square quadratic function
WebThe general form of a quadratic function presents the function in the form f(x) = ax2 + bx + c where a, b, and c are real numbers and a ≠ 0. If a > 0, the parabola opens upward. If a < 0, the parabola opens downward. We can use the general form of a parabola to find the equation for the axis of symmetry. WebMay 20, 2024 · There are actually four ways to solve a quadratic equation: taking the square root, factoring, completing the square, and the quadratic formula. Unfortunately, taking the square root and factoring only work in certain situations. For example, let’s look at the following quadratic equation: x 2 + 6 x = − 2
