Hi!
Could someone please solve this equation for me and try to explain how you did that. 4*(x-1)^2+1/3=7/9
I do know the answer for this equation. But I don't know how to think when solving it and how to get the answer.
Thank you very much skeeter!
Never realised that it was so easy.
HallsofIvy: Well, not really :P I just translated the name we use for this kind of equations here in Sweden directly to english. So It maybe isn't very correct

Okey, here you've got one more equation to help me out with. I have to say that this book really sucks at explaining (and so does my math teacher also, sadly enough).
2x^2+4x+40=3x^2-2x
And by the way. It would be extreamly nice if you could help me out two factorizing problems also:
1. 2x+2a2b(x+a)
2. a^(x+2)-a^(2x)
