TO make things clearer, be sure to use parentheses especially in denominators of complex fractions.
\n" ); document.write( "I think this is the expression you're trying to simplify.
\n" ); document.write( " $\"x%2B1%2F%28x%5E2-4%29+%2B+x%2F%283x%2B6%29\"$
\n" ); document.write( "When adding/subtracting with fractions, you need a common denominator.
\n" ); document.write( "In this case, the first expression has a denominator of $\"1\"$ .
\n" ); document.write( "Second expression: $\"x%5E2-4=%28x%2B2%29%28x-2%29\"$
\n" ); document.write( "Third expression: $\"3x%2B6=3%28x%2B2%29\"$
\n" ); document.write( "So a common denominator would be $\"%28x%2B2%29%28x-2%29\"$ .
\n" ); document.write( "
