So you get eight X square. Is he told to 96 the what if I eat, You know that it's X square is equal to 96 8 one 16 to called 12. We're gonna square root both sides. You know that it's not a perfect square root, so you get X square. Square root is equal to square root of four times a squirt of three because the square root of four can be split into two and two, so we know that it's X is equal to plus minus two square root of three.
