First, write the equation in standard form: $\"ax%5E2%2Bbx%2Bc+=+0\"$
\n" ); document.write( " $\"4x%5E2-13x-12+=+0\"$ Solve by factoring.
\n" ); document.write( " $\"%284x%2B3%29%28x-4%29+=+0\"$ Apply the zero products principle.
\n" ); document.write( " $\"4x%2B3+=+0\"$ or $\"x-4+=+0\"$
\n" ); document.write( "Therefore:
\n" ); document.write( " $\"4x+=+-3\"$
\n" ); document.write( " $\"x+=+-3%2F4\"$
\n" ); document.write( "Or
\n" ); document.write( " $\"x+=+4\"$ \n" ); document.write( "

\n" );
