Thanks very much for doing that! I get where I went wrong now. You're a star!

Thanks!

Could I just ask, though - how would I do it using a method like the one on this page: http://www.mathsisfun.com/algebra/completing-square.html

This is the method I have been using, you see, and so I would really love it if somebody could explain it so that I could find out where my error is - I need to be able to do these questions!!

Thanks again!

The question is:

3x² - 24x + 47

and for the life of me, I can't get the right answer:
3 ( x - 4 )² - 1

I can get the x - 4 part no problem, but am having difficulty getting any of my numbers to add to minus one, no matter what process I go through! Could somebody please help me by showing me the working to end up with -1?

Thank-you in advance!
