Add/subtract:
\n" ); document.write( " $\"%285%2Fx%29-%284%2F%28x%2B1%29%29%2B%285%2F%28x%5E2%2Bx%29%29\"$ To add/subtract fractions, you need to find the LCD (Lowest Common Denominator), which, in this case, is $\"x%5E2%2Bx+=+x%28x%2B1%29\"$ , so you would multiply the first fraction by $\"%28x%2B1%29%2F%28x%2B1%29\"$ , and the second fraction by $\"x%2Fx\"$ to get:
\n" ); document.write( "

which simplifies to:
\n" ); document.write( " $\"%285x%2B5-4x%2B5%29%2F%28x%28x%2B1%29%29\"$ which further simplifies to:
\n" ); document.write( " $\"%28x%2B10%29%2F%28x%28x%2B1%29%29\"$ or $\"highlight%28%28x%2B10%29%2F%28x%5E2%2Bx%29%29\"$ \n" ); document.write( "
