If anyone can figure out why this formula won't work on Graal.

PHP Code:

//#CLIENTSIDE
function onPlayerChats()
{
 if (player.chat == "/quad")
 {
  Quad();
 }
}

function Quad()
{
 temp.a = 5;
 temp.b = 27;
 temp.c = 10;
 temp.x1 = (-temp.b + ((temp.b*temp.b-4*temp.a*temp.c)^0.5))/2*temp.a;
 temp.x2 = (-temp.b - ((temp.b*temp.b-4*temp.a*temp.c)^0.5))/2*temp.a;
 player.chat = "Solution is:" SPC temp.x1 SPC temp.x2;
}
