\n" );
document.write( "If the area is 55 square centimeters, find the length and width 
\n" );
document.write( "   x(3x-4) = 55
\n" );
document.write( "   3x^2 - 4x - 55 = 0
\n" );
document.write( " (3x + 11)(x-5) = 0
\n" );
document.write( "          x = 5, throwing out the negative solution for unit of measure
\n" );
document.write( " width is 5 and length is 11    \n" );
document.write( "

\n" );
