Use a substitution, let $\"u%5E2=x\"$ , $\"u=sqrt%28x%29\"$
\n" ); document.write( " $\"%28u%5E2-9%29%2F%28u-3%29=%28%28u-3%29%28u%2B3%29%29%2F%28u-3%29\"$
\n" ); document.write( " $\"%28u%5E2-9%29%2F%28u-3%29=u%2B3\"$
\n" ); document.write( " $\"%28x-9%29%2F%28sqrt%28x%29-3%29=sqrt%28x%29%2B3\"$
\n" ); document.write( " \n" ); document.write( "
