Original fraction,
\n" ); document.write( "\"X%2F%28X%2B2%29\"
\n" ); document.write( "New fraction,
\n" ); document.write( "\"%28X-1%29%2F%28X%2B2%2B3%29=%28X-1%29%2F%28X%2B5%29\"
\n" ); document.write( "So then,
\n" ); document.write( "\"%28X-1%29%2F%28X%2B5%29=%281%2F2%29%28X%2F%28X%2B2%29%29\"
\n" ); document.write( "\"2%28X-1%29%28X%2B2%29=X%28X%2B5%29\"
\n" ); document.write( "\"2%28X%5E2%2B2X-X-2%29=X%5E2%2B5X\"
\n" ); document.write( "\"2X%5E2%2B2X-4=X%5E2%2B5X\"
\n" ); document.write( "\"X%5E2-3X-4=0\"
\n" ); document.write( "\"%28X-4%29%28X%2B1%29=0\"
\n" ); document.write( "Two solutions:
\n" ); document.write( "\"X-4=0\"
\n" ); document.write( "\"X=4\"
\n" ); document.write( "and
\n" ); document.write( "\"X%2B1=0\"
\n" ); document.write( "\"X=-1\"
\n" ); document.write( "So the original fraction was
\n" ); document.write( "\"4%2F%284%2B2%29=4%2F6=2%2F3\"
\n" ); document.write( "or
\n" ); document.write( "\"-1%2F%28-1%2B2%29=-1%2F1=-1\"
\n" ); document.write( "
\n" ); document.write( "
\n" );
