L.O To be able to solve quadratic equations through factorising, completing the square and using the quadratic formulae.

On the previous sheet we learnt how to factorise quadratic equations. If you are told to solve a problem like x2 + 6x + 8 = 0 then the way to tackle it is to factorise first. After factorising you get (x+4) (x+2) = 0 you have to work out different values of x that can go in the brackets that will make the equation work.

Example 1:

Solve the equation x(3x-2)=0

Solve the equation x(3x-2)=0

Example 2:

Solving by Completing the Square

Sometime the quadratic equation can’t easily be factorised, in that case you have to “complete the square”, this is denoted by the following equation:
