DETAILED EXPLANATION

\n" ); document.write( "
Look at \"highlight_red%28+%285%2Ac-7%29%2A%28-highlight_red%28+3+%29%29+%29\".
Remove unneeded parentheses around factor \"highlight_red%28+3+%29\"
It becomes \"-%285%2Ac-7%29%2Ahighlight_green%28+3+%29\".
\n" ); document.write( "
Look at \"-highlight_red%28+%285%2Ac-7%29%2A3+%29\".
Expanded term \"-3\" by using associative property on \"%285%2Ac-7%29\"
It becomes \"-highlight_green%28+3%2A5%2Ac+%29%2Bhighlight_green%28+3%2A7+%29\".
\n" ); document.write( "
Look at \"-highlight_red%28+3+%29%2Ahighlight_red%28+5+%29%2Ac%2B3%2A7\".
Multiplied numerator integers
It becomes \"-highlight_green%28+15+%29%2Ac%2B3%2A7\".
\n" ); document.write( "
Look at \"-15%2Ac%2Bhighlight_red%28+3+%29%2Ahighlight_red%28+7+%29\".
Multiplied numerator integers
It becomes \"-15%2Ac%2Bhighlight_green%28+21+%29\".
Result: \"-15%2Ac%2B21\"
