You can put this solution on YOUR website!
For future reference, don't be shy about using parentheses especially with complicated fraction expressions.
\n" ); document.write( "I think you mean like this,
\n" ); document.write( "1/(x+7) + 5/(x+6) = -1/(x^2+13x+42)

\n" ); document.write( "However, one of the implicit assumptions we made was that x did not equal -6 and -7 which would cause a division by zero.
