This video is all about completing the square and forms part of the higher level playlist of the same name. I've also added to the playlist on GCSE higher revision.

This question is a little difficult as you need to work with fractions. On that basis it's likely that this would be around level 7 - 9, although there's only a few marks available.

Write in the form a(x + p)squared + q

4xsquared + 8x - 11

I hope the video helps and please do leave a comment - thanks!
