Solve the quadratic equation by completing the square.

3x2 - 6x - 4 = 0

-0.53, 2.53 to the nearest hundredth.

Step-by-step explanation:

3x^2 - 6x - 4 = 0

3 (x^2 - 2) - 4 = 0

3 [ (x - 1) ^2 - 1] = 4

3 (x - 1) ^2 - 3 = 4

3 (x - 1) ^2 = 7

(x - 1) ^1 = 7/3

x - 1 = + / - √ (7/3)

x = + / - √ (7/3) + 1

x = 2.53, - 0.53.
