You can put this solution on YOUR website!
$\"%28q%5E2-q-1%29%2Fq%5E3\"$ - $\"%282q%5E2%2B2q-1%29%2Fq%5E3\"$
\n" ); document.write( ":
\n" ); document.write( "They have the same denominators, so you can write it
\n" ); document.write( " $\"%28%28q%5E2-q-1%29-%282q%5E2%2B2q-1%29%29%2Fq%5E3\"$
\n" ); document.write( "Removing the brackets changes the signs after the minus
\n" ); document.write( " $\"%28%28q%5E2-q-1-2q%5E2-2q%2B1%29%29%2Fq%5E3\"$
\n" ); document.write( "Group and combine like terms
\n" ); document.write( " $\"%28%28q%5E2-2q%5E2-q-2q-1%2B1%29%29%2Fq%5E3\"$ = $\"%28%28-q%5E2-3q%29%29%2Fq%5E3\"$
\n" ); document.write( "Factor out -q, cancel
\n" ); document.write( " $\"%28-q%28q-3%29%29%2Fq%5E3\"$ = $\"-%28q%2B3%29%2Fq%5E2\"$ , essentially the same as $\"%28-q-3%29%2Fq%5E2\"$ which you had \n" ); document.write( "

\n" );
