\n" );
document.write( "Hi,
\n" );
document.write( "x+2 + x^2-x + 2x+1 = 18cm
\n" );
document.write( " x^2 + 2x -15 = 0   
\n" );
document.write( "(x+5)(x-3) = 0   (Tossing out x = -5 that results in negative lengths)
\n" );
document.write( "     x = 3
\n" );
document.write( "lengths of each side:   5cm, 6cm, 7cm
\n" );
document.write( "CHECKING our answer***
\n" );
document.write( "5cm + 6cm + 7cm = 18cm
\n" );
