Multiply the rational expression:
\n" ); document.write( " $\"%28%28-2a%5E2%29%2F3a%5E2%29%2820a%2F15a%5E3%29\"$ If you rewrite this as follows, then perhaps it will make it easier to see what can be cancelled:
\n" ); document.write( " $\"%28%28-2%2Aa%2Aa%29%2F%283%2Aa%2Aa%29%29%2820%2Aa%2F%2815%2Aa%2Aa%2Aa%29%29\"$ Cancel an a in the top with an a in the bottom, one-for-one.
\n" ); document.write( " $\"%28%28-2%29%2F3%29%2820%2F%2815%2Aa%2Aa%29%29\"$ Now do the numbers. A common factor of 20 and 15 is 5, so cancel 5's.
\n" ); document.write( " $\"%28%28-2%29%2F3%29%284%2F%283%2Aa%2Aa%29%29\"$ Finally, multiply the numerators and the denominators.
\n" ); document.write( " $\"%28-8%29%2F%289a%5E2%29\"$ \n" ); document.write( "

\n" );
