$\"2L%5E2-5L+=+3\"$ Subtract 3 from both sides.
\n" ); document.write( " $\"2L%5E2-5L-3+=+0\"$ Factor the quadratic equation.
\n" ); document.write( " $\"%282L%2B1%29%28L-3%29+=+0\"$
\n" ); document.write( " $\"2L%2B1+=+0\"$ or $\"L-3+=+0\"$ so...
\n" ); document.write( " $\"2L+=+-1\"$ or $\"L+=+3\"$ Discard the negative solution, so...
\n" ); document.write( " $\"highlight%28L+=+3%29\"$ is the length of the rectangle. \n" ); document.write( "

\n" );
