$\frac{2^2-x^2}{2+x}=0$
Learn how to solve equations problems step by step online. Find the roots of (2^2-x^2)/(2+x). Find the roots of the polynomial \frac{2^2-x^2}{2+x} by putting it in the form of an equation and then set it equal to zero. Calculate the power 2^2. 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 2 from both sides of the equation.
