I want to help you achieve amazing GCSE results!

This is a harder topic so it might be best to book a session with a tutor even just half an hour and you should be able to really get the hang of it. I’m available for sessions if you’re interested? However here is an explanation: For example xΒ²+4x+6=0 To complete the square you take x + half of the coefficient of x,so 2 in this case, and put them in a bracket and square it. (X+2)Β² which means (X+2)(X+2) Expand this and see what you have to do to it to get xΒ²+4x+6=0 xΒ²+4x+4 is the expanded form so you need to add two to get to xΒ²+4x+6=0 (X+2)Β² +2 = 0 is the completed square
