Correct Answer: Option B

Explanation

3x2 + 6x - 2 = 0

Using almighty formula i.e. x = \(\frac{b \pm \sqrt{b^2 - 4ac}}{2a}\)

a = 3, b = 6, c = -2

x = \(\frac{-6 \pm \sqrt{6^2 - 4(3)(-2)}}{2(3)}\)

x = \(\frac{-6 \pm \sqrt{36 + 24}}{6}\)

x = \(\frac{-6 \pm \sqrt{60}}{6}\)

x = \(\frac{-6 \pm \sqrt{4 \times 15}}{6}\)

x = \(-1 \pm \frac{\sqrt{15}}{3}\)
