## Step-by-step explanation

Problem to solve:

$\frac{x^2+2x+1}{x^2+1}$

Learn how to solve polynomial long division problems step by step online.

$\Delta=b^2-4ac=2^2-4\left(1\right)\left(1\right) = 0$

Learn how to solve polynomial long division problems step by step online. Simplify the expression (x^2+2x+1)/(x^2+1). The trinomial x^2+2x+1 is a perfect square trinomial, because it's discriminant is equal to zero. Using the perfect square trinomial formula. Factoring the perfect square trinomial. Divide \left(x+1\right)^{2} by x^2+1.

$1+\frac{-1}{x^2+1}$
