Answer: Option B (
x=1±
i√(3))


Explanation:

1. To solve this problem you must use the Quadratic formula, which is used to solve quadratic equation. This formula is shown below:


x=\frac{-b+/-\sqrt{b^(2)-4ac}}{2a}

2. Make the equation equal to zero. So, you must rewrite it as following:


6x^(2)-12x+24=0

3. Now, you must substitute values. Then, you have:


a=6\\b=-12\\c=24


x=\frac{-(-12)+/-\sqrt{(-12)^(2)-4(6)(24)}}{2(6)}

4. Then,you obtain the following result:


x=1±
i√(3)
