First of all, notice what each term has in common:
\n" ); document.write( "a multiple of \"3a\"
\n" ); document.write( "factor that out: \"%283a%29%28x%5E2-14%2B5x%29\"=\"%283a%29%28x%5E2%2B5x-14%29\"\r
\n" ); document.write( "\n" ); document.write( "For factoring \"x%5E2%2B5x-14\", we list the possible numbers that multiply to 14:
\n" ); document.write( "1, 2, 7, 14.
\n" ); document.write( "Which two of these, when taking one negative, add to get +5? -2 and +7!\r
\n" ); document.write( "\n" ); document.write( "Thus, \"x%5E2%2B5x-14\" factors to \"%28x%2B7%29%28x-2%29\", which makes the final expression:\r
\n" ); document.write( "\n" ); document.write( "\"3a%28x%2B7%29%28x-2%29\"
\n" ); document.write( "
\n" );
