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!

Nevermind!

Forgot about the (a+b)^2 = a^2 + 2ab+b^2 rule!
