WebFeb 10, 2024 · A quadratic equation is a polynomial equation in a single variable where the highest exponent of the variable is 2. [1] There are three main ways to solve quadratic equations: 1) to factor the quadratic equation if you can do so, 2) to use the quadratic formula, or 3) to complete the square. WebSimply put the root in place of "x": the polynomial should be equal to zero. Example: 2x 3 −x 2 −7x+2 The polynomial is degree 3, and could be difficult to solve. So let us plot it first: The curve crosses the x-axis at three points, and one of them might be at 2. We can check easily, just put "2" in place of "x": f (2) = 2 (2) 3 − (2) 2 −7 (2)+2
