So, if you have:
\n" ); document.write( "Subtract -5a^2-5a+7 from -8a^2-5a+4
\n" ); document.write( ".
\n" ); document.write( "This would be equivalent to:
\n" ); document.write( "(-8a^2-5a+4) - (-5a^2-5a+7)
\n" ); document.write( "Start by distributing the negative sign (-) to terms inside the parenthesis:
\n" ); document.write( "(-8a^2-5a+4) + 5a^2+5a-7
\n" ); document.write( "-8a^2-5a+4 + 5a^2+5a-7
\n" ); document.write( "Combine like-terms:
\n" ); document.write( "(-8a^2+5a^2)+(-5a+5a)+(4-7)
\n" ); document.write( "(-3a^2)+(0)+(-3)
\n" ); document.write( "Resulting in:
\n" ); document.write( "-3a^2 - 3\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
