Countdown to Exams - Day 63 - Solving by factorising and the Quadratic formula

In today's blog, we take a look at solving quadratics using two methods. The first method to explore is solving by factorising. This means that we need to put the quadratic into double brackets and then solve to find values for x. If you end up with a quadratic that cannot be factorised then you will need to use the Quadratic formula method.

It is important to establish the values of a, b and c that are needed to substitute into the formula. You will need to memorise the formula as you will not be given this in the exam. Remember that when using the quadratic formula, you will need to do two calculations one where you ADD the square root and one where you SUBTRACT the square root. 

Matt delves a little deeper onto solving quadratics by factorising and by using the quadratic formula in the video below.
