Okay. This problem here with God and oops Don't do that guy. Let's hear we've got and I plus an I squared plus and I cubed plus an eye to the fourth. So here we have this eye that doesn't go anywhere And then we know that I squared is a negative one And then we know that I squared was negative one and then another I would be a negative I And then we have this ID of the fourth, which we know is one because it's I square toe a negative one times eight negative one, which is one. So you see here that all of these guys cancel out and we're left with zero.
