\"+1%2F%28x%2B3%29+-+1%2F%28x%2B4%29+=+1%2F2\"
\n" ); document.write( "==> \"2%28%28x%2B4%29-%28x%2B3%29%29=%28x%2B3%29%28x%2B4%29\"
\n" ); document.write( "==> \"2+=+x%5E2+%2B+7x+%2B+12\"
\n" ); document.write( "==> \"0+=+x%5E2+%2B+7x+%2B+10\"
\n" ); document.write( "<==> 0 = (x + 2)(x+ 5) ==> x = -2, -5.
\n" ); document.write( "Both values will never make the denominator 0, so they are the final answers.
\n" ); document.write( "
