$\"%2810%2Bsqrt%2820%29%29-%284-sqrt%2845%29%29\"$ Start with given problem
\n" ); document.write( " $\"%2810%2Bsqrt%284%2A5%29%29-%284-sqrt%289%2A5%29%29\"$ Display radicand as product
\n" ); document.write( " $\"%2810%2Bsqrt%284%29%2Asqrt%285%29%29-%284-sqrt%289%29%2Asqrt%285%29%29\"$ Break up square root
\n" ); document.write( " $\"%2810%2B2%2Asqrt%285%29%29-%284-3%2Asqrt%285%29%29\"$ Take square root of perfect square
\n" ); document.write( " $\"10%2B2%2Asqrt%285%29-4%2B3%2Asqrt%285%29%29\"$ Distribute negative
\n" ); document.write( " $\"10-4%2B2%2Asqrt%285%29%2B3%2Asqrt%285%29%29\"$ Group like terms
\n" ); document.write( " $\"6%2Bsqrt%285%29%282%2B3%29\"$ Group $\"sqrt%285%29\"$ terms together (note: $\"sqrt%285%29\"$ is like x. ie 3x+2x=x(3+2))
\n" ); document.write( " $\"6%2B5%2Asqrt%285%29\"$ This is what you should get
\n" ); document.write( "Hope this makes sense. \n" ); document.write( "

\n" );
