Factorising Method When using the factorising method to solve a quadratic equation, the equation must always equal zero If it doesn’t, re-arrange the equation to make it equal to zero!

Quadratics This quadratic equation would have two possible solutions This quadratic equation would have one possible solution This quadratic equation would have no possible solutions

Factorising Method 1. Factorise Since the two brackets multiplied together equals zero, at least one bracket must equal zero, so… 2. Solve the equations

Factorising Method

On your whiteboards, solve the following quadratic equations:
