To solve any quadratic equation, convert it into standard form ax 2 + bx + c 0, find the values of a, b, and c, substitute them in the roots of quadratic equation formula and simplify. See how to graph, find roots and complex solutions with examples and interactive tools. It is based on a right triangle, and states the relationship among the lengths of the sides as \(a^2+b^2=c^2\), where \(a\) and \(b\) refer to the legs of a right triangle adjacent to the \(90°\) angle, and \(c\) refers to the hypotenuse. The quadratic formula says the roots of a quadratic equation ax 2 + bx + c 0 are given by x (-b ± (b 2 - 4ac)) /2a. Learn how to solve quadratic equations using the standard form, the quadratic formula, the discriminant and the plus/minus rule. See examples, exercises and a note about the zero-product property. One of the most famous formulas in mathematics is the Pythagorean Theorem. The quadratic formula is a general formula used for solving the quadratic equation: x b b 2 4 a c 2 a. Learn how to solve factored quadratic equations like (x-1) (x+3)0 and how to use factorization methods to solve other forms of equations.
