Answer:

x=0.66+1.88i

x=0.66-1.88i

Explanation:

Given

3
x^(2)-4x+12=0

using the Quadratic Formula where

a = 3, b = -4, and c = 12


x=-b±
\sqrt{b^(2)-4ac } /2a\\

x=-(-4)±
\sqrt{(-4)^(2)-4(3)(12) } /2(3)

x=4±
√(16-144) /6

x=-4±
√(128) /6


b^(2) -4ac<0\\

x=-4±
8√(2) i/6


x=(2)/(3)±
(4√(2)i )/(3)

Which becomes,

x=0.66+1.88i

x=0.66-1.88i

The value of x will be x=0.66+1.88i

x=0.66-1.88i
