\n" ); document.write( "(Finding the lengths of all legs of a right triangle)
\n" ); document.write( "=======
\n" ); document.write( "X^2+(x+6)^2=(x+12)^2
\n" ); document.write( "------
\n" ); document.write( "x^2 + x^2 + 12x + 36 = x^2 + 24x + 144
\n" ); document.write( "------
\n" ); document.write( "x^2 - 12x - 108 = 0
\n" ); document.write( "-------
\n" ); document.write( "(x-18)(x+6) = 0
\n" ); document.write( "-------
\n" ); document.write( "Positive solution::
\n" ); document.write( "x = 18
\n" ); document.write( "--------
