$\"x%2Asqrt%2818%29-3%2Asqrt%288x%5E2%29\"$
\n" ); document.write( " $\"x%2Asqrt%282%2A9%29-3%2Asqrt%282%2A4%2Ax%5E2%29\"$ Rewrite terms inside square root
\n" ); document.write( " $\"x%2Asqrt%282%29%2Asqrt%289%29-3%2Asqrt%282%29%2Asqrt%284%29%2Asqrt%28x%5E2%29\"$ Rewrite roots using $\"sqrt%28xy%29=sqrt%28x%29sqrt%28y%29\"$
\n" ); document.write( " $\"x%2Asqrt%282%29%2A3-3%2Asqrt%282%29%2A3%2Ax\"$ Notice how we have a common term of $\"sqrt%282%29\"$
\n" ); document.write( " $\"3x%2Asqrt%282%29-9x%2Asqrt%282%29\"$ combine these terms
\n" ); document.write( " $\"%283x-9x%29%2Asqrt%282%29\"$ Simplify
\n" ); document.write( " $\"-6x%2Asqrt%282%29\"$ \n" ); document.write( "

\n" );
