You can solve this quadratic equation by factoring.
\n" ); document.write( " $\"4x%5E2+=+13x%2B12\"$ First, rewrite in standard form.
\n" ); document.write( " $\"4x%5E2-13x-12+=+0\"$ Now factor.
\n" ); document.write( " $\"%284x%2B3%29%28x-4%29+=+0\"$ Apply the zero product principle.
\n" ); document.write( " $\"4x%2B3+=+0\"$ and/or $\"x-4+=+0\"$
\n" ); document.write( "If $\"4x%2B3+=+0\"$ then $\"4x+=+-3\"$ so $\"x+=+-3%2F4\"$
\n" ); document.write( "If $\"x-4+=+0\"$ then $\"x+=+4\"$ \r
\n" ); document.write( "\n" ); document.write( "The roots are:
\n" ); document.write( " $\"x+=+-3%2F4\"$
\n" ); document.write( " $\"x+=+4\"$ \n" ); document.write( "

\n" );
