Question
Add or subtract. Write each answer in lowest terms. See Examples 5 and $8 .$65. $\frac{2}{x-y^{2}}+\frac{7}{y^{2}-x}$
Step 1
We can rewrite the second fraction to have the same denominator as the first by factoring out a negative one. So, $\frac{7}{y^{2}-x} = \frac{-7}{x-y^{2}}$. Show more…
