$\frac{y^2-x^2}{y+x}=0$
Learn how to solve equations problems step by step online. Find the roots of (y^2-x^2)/(y+x). Find the roots of the polynomial \frac{y^2-x^2}{y+x} by putting it in the form of an equation and then set it equal to zero. The difference of the squares of two terms, divided by the sum of the same terms, is equal to the difference of the terms. In other words: \displaystyle\frac{a^2-b^2}{a+b}=a-b.. We need to isolate the dependent variable , we can do that by simultaneously subtracting -x from both sides of the equation. x+0=x, where x is any expression.
