WebHow do you calculate a quadratic equation? To solve a quadratic equation, use the quadratic formula: x = (-b ± √ (b^2 - 4ac)) / (2a). What is the quadratic formula? The quadratic formula gives solutions to the quadratic equation ax^2+bx+c=0 and is written in the form of x = (-b ± √ (b^2 - 4ac)) / (2a) Does any quadratic equation have two solutions? WebCreated by. Secondary Math Solutions. This is a one-sided document intended to provide students with practice on transforming the quadratic parent function.
