Solve Quadratic Equations: Slide & Divide

Date: 2021-02-08

In this video I show you a new and very easy way of solving quadratic equations that can be used in Junior Cert maths right up to Leaving Cert Higher Level Maths. (it's new to me but has been around years) It's called the slide & divide method, you slide the coefficient of the x square term up and multiply it by the constant. Then you factorise the new quadratic equation. You then take the number that was the coefficient of the x square and you divide it into the constant in each of the factors. If it goes in great, if not you slide it back to in front of the x term in that factor.
