The possible value or values of y in the quadratic equation 4 – 4y – y2 = 0 is y = –2 + 2 2, y = 2 2 2.

Solution: y = -(-4) ± ((-4)² - 4(4)(-1)) 2(-1); y = 4 ± (16 + 16) -2; y = 4 ± (32) -2; y = 4 ± 4 (2)-2; y = 4 + 4 (2) or y = 4 - 4 (2)-2.

Solution: y = -(-4) ± ((-4)² - 4(4)(-1)) 2(-1); y = 4 ± (16 + 16) -2; y = 4 ± (32) -2; y = 4 ± 4 (2)-2; y = 4 + 4 (2) or y = 4 - 4 (2)-2.
