SOLUTION: Please help me write in lowest terms: x^2-y^2/x^2+2xy+y

Question 628968: Please help me write in lowest terms:
x^2-y^2/x^2+2xy+y
Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!

The numerator is the difference of two squares, hence the numerator is the product of a pair of conjugate binomials.

The denominator is a perfect square trinomial, factor it.

Once you have factored both numerator and denominator, eliminate identical factors in both numerator and denominator. Remember to set the eliminated factor equal to zero and solve for

so that you know what value(s) to exclude from the domain of your resulting expression.
