First the left side...
\n" ); document.write( "(x+2)(x+3)
\n" ); document.write( "Use the distributive property
\n" ); document.write( "X^2+2x+3x+6
\n" ); document.write( "simplify
\n" ); document.write( "x^2+5x+6\r
\n" ); document.write( "\n" ); document.write( "Now the right side
\n" ); document.write( "(x+7)(x-4)
\n" ); document.write( "Use the distributive property
\n" ); document.write( "X^2+7x-4x-28
\n" ); document.write( "Simplify
\n" ); document.write( "X^2+3x-28\r
\n" ); document.write( "\n" ); document.write( "Put them together...
\n" ); document.write( "X^2+5x+6=X^2+3x-28
\n" ); document.write( "Subtract x^2 on both sides
\n" ); document.write( "5x+6=3x-28
\n" ); document.write( "Subtract 3x on both sides
\n" ); document.write( "2x+6=-28
\n" ); document.write( "Subtract 6 on both sides
\n" ); document.write( "2x=-34
\n" ); document.write( "Divide both sides by 2
\n" ); document.write( "x=-17 \n" ); document.write( "

\n" );
