Homework Statement



(2x^2+4x+2)/x+1 = l

Simplify the equation for l. I do not want to solve it, just simplify.

Homework Equations





The Attempt at a Solution



I actually reduced the equation this far already, and the back of the book says I have gotten the equation right up to this point, but then it gives the answer, but not the steps to get there. The ANSWER: 2(x+1) .... I do not understand how to get that .

can you simplify (x^2+2x+1) further? (think of perfect squares)
