WebDec 2, 2024 · Steps. 1. Start with the standard form of a general quadratic equation. While any equation with an term in it qualifies as quadratic, the standard form sets everything to 0. Remember that are coefficients that can be any real number, so don't substitute any numbers in for them - we want to work with the general form. WebA quadratic function is graphically represented by a parabola with vertex located at the origin, below the x -axis, or above the x -axis. Therefore, a quadratic function may have one, two, or zero roots. When we are asked to solve a quadratic equation, we are really being asked to find the roots.
