You can put this solution on YOUR website!
(!) Use grouping symbols, parentheses to separate numerator and denominator.
\n" ); document.write( "(!) Algebra is not formal written English; do not capitalize variable when it is first character on a new line, unless the capitalized form IS the variable assigned or expected.
\n" ); document.write( "(!) The site's rendering tag is triple left and triple right curly braces.\r

\n" ); document.write( "\n" ); document.write( "Your rational expression in pure text form:
\n" ); document.write( "(x^2+7x-18)/(x^2-11x+18)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Your expression inside the rendering tag:
\n" ); document.write( " $\"%28x%5E2%2B7x-18%29%2F%28x%5E2-11x%2B18%29\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The values of x which must be EXCLUDED are any (two specific ones) which make the denominator 0. Your denominator is factorable:
\n" ); document.write( " $\"x%5E2-11x%2B18=%28x-2%29%28x-9%29\"$
\n" ); document.write( "since this is the denominator,
