WebOnce you have it in vertex form you should have something like (x - h)^2 + k = 0 (since zeros are where f (x) = 0), so you solve from farthest from x to closest, so subtract k, (x-h)^2 = -k, take square root, so x - h = ± √-k, and finally add h, so x = h ± √-k. WebHere is one example of a quadratic equation with no real solution: x2 + 2x + 5 = 0 In this case, a = 1, b = 2, and c = 5. This gives us: b2 = (2)2 = 4 and 4ac = 4 (1) (5) = 20 So, b 2 < 4ac (since 4 < 20), and thus the discriminant is negative. This means that the quadratic has no …
