Quadratic equations a quadratic equation in x is an equation that can be written in the standard from ax 2 bx c 0 where a b and c are real numbers with a 0 a quadratic equation in x is also called a second degree polynomial equation in x the zero product principle. Quadratic equations this unit is about the solution of quadratic equations these take the form ax 2 bx c 0 we will look at four methods solution by factorisation solution by completing the square solution using a formula and solution using graphs video tutorial 51 mins. Solving equations and inequalities solutions and solution sets linear equations applications of linear equations equations with more than one variable quadratic equations part i quadratic equations part ii quadratic equations a summary applications of quadratic equations equations reducible to quadratic in form equations with . Make both equations into y format set them equal to each other simplify into 0 format like a standard quadratic equation solve the quadratic equation use the linear equation to calculate matching y values so we get xy points as answers
