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!
