So I have a problem which is to simplify:
(x^2+2x+1) / (x+1)
What I did was this:
x(x+2)+1 / x+1
x+2+1 / 1
x+2 / 1
According to the book you are suppost to do it like this:
(x+1)^2 / x+1
x+1
But doesn't that mean you just remove 2x out of everything?
I think both mine and the books calculations are wrong, or am I wrong?
Glad for answers!
