## How to work with the Quadratic Formula

You are in the final minute of a rugby match and you have to kick a perfect drop goal. The last thing you will be thinking about is your maths lessons. However, to score you must kick the ball at the correct angle and velocity so that when it travels a  certain distance  to the goal it is at the right height to go over the goalposts. To do this you must solve a quadratic equation! Or practice….. a lot!   Quadratic equations are actually used in everyday life, when calculating areas, determining a product’s profit or formulating the speed of an object. They can also be used for defining the shape of parabolic mirrors, reflecting telescopes and satellite dishes.

GCSE Maths students – you need to be able to factorise using the quadratic formula. Our new guide, “How to work with the Quadratic Formula” can help. It includes the formula, and explains how to use it. Included, as always are questions to try, and answers to check your understanding.
