1. Howdy ,

I have been putting quadratic equations into the form for complete the square.

What would I do for:

as the a > 1, how would I go about this, is there a different rule for this?

Thanks

Just pull the factor of two out, like this:

then complete the square on the inside bit and multiply out, you'll end up with something of the form

Edit to add: when I said a,b in my post I mean general numbers a and b, not the coefficients of the quadratic.
3. just expand

a( x - b )2 + c

and compare the relevant sections to find a,b,c
