a) x^{2}-2=2 x-4

Question

a) x^{2}-2=2 x-4

Accepted Answer

Step:1 ：Rewrite the equation in the standard form: (x^2 - 2x - 2 = 0)Step:2 ：Use the quadratic formula: (x = frac{-b pm sqrt{b^2 - 4ac}}{2a}), where (a = 1), (b = -2), and (c = -2)Step:3 ：Calculate the discriminant: (Delta = b^2 - 4ac = 12)Step:4 ：Find the solutions for x: (x approx 2.732) and (x approx -0.732)Step:5 ：(boxed{x approx 2.732, x approx -0.732})
