document.write( "Let x represent the length of each side of the square. (x+12ft) the diagonal.
\n" );
document.write( "applying the Pythagorean theorem (with the diagonal being the hypotenuse)
\n" );
document.write( "x^2 + x^2 = (x + 12)^2
\n" );
document.write( "2x^2 = x^2 + 24x + 144ft^2
\n" );
document.write( "x^2 -24x - 144  = 0
