Solve by factoring:
\n" ); document.write( " $\"a%5E2-3a-18+=+0\"$ Factor the trinomial.
\n" ); document.write( " $\"%28a-6%29%28a%2B3%29+=+0\"$ Apply the zero product rule.
\n" ); document.write( " $\"a-6+=+0\"$ or $\"a%2B3+=+0\"$ so...
\n" ); document.write( " $\"highlight%28a+=+6%29\"$ or $\"highlight%28a+=+-3%29\"$ \n" ); document.write( "

\n" );
