Restating your original problem just to make it easier to read:
\n" ); document.write( " $\"+sqrt%288%29%2Asqrt%282%29+-+7+\"$ \r
\n" ); document.write( "\n" ); document.write( "That can be simplified by first prime factorizing 8, which results in the prime factors of 2 * 2 * 2. So now the problem can be rewritten by substituting the prime factors for 8:
\n" ); document.write( " $\"+sqrt%282%2A2%2A2%29%2Asqrt%282%29+-+7+\"$ \r
\n" ); document.write( "\n" ); document.write( "You can split those all out separately:
\n" ); document.write( " $\"+sqrt%282%29%2Asqrt%282%29%2Asqrt%282%29%2Asqrt%282%29+-+7+\"$ \r
\n" ); document.write( "\n" ); document.write( "Since $\"sqrt%282%29%2Asqrt%282%29+=+2\"$ , the above problem can be simplified as:
\n" ); document.write( " $\"+2%2A2+-+7\"$ \r
\n" ); document.write( "\n" ); document.write( "Which can then be further simplified as:
\n" ); document.write( " $\"-3\"$ \n" ); document.write( "

\n" );
