You can put this solution on YOUR website!
x^2 = 25 ==> x = -5, 5\r
\n" ); document.write( "\n" ); document.write( "y^2 = 16 ==> y = -4, 4\r
\n" ); document.write( "\n" ); document.write( "z^2 = 0 ==> z = -3, 3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "max((x+y+z)^2) = (3+4+5)^2 = 144
