I'm assuming the third side is the hypotenuse.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(5x)^2 + (x + 8)^2 = (5x - 4)^2
\n" ); document.write( "25x^2 + x^2 + 16x + 64 = 25x^2 - 40x + 16
\n" ); document.write( "x^2 + 16x + 64 = -40x + 16
\n" ); document.write( "x^2 + 56x + 48 = 0\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Use the quadratic formula to find x.
