Solve. Round results to the nearest thousandth.
-$$3 x ^ { 2 } - 6 x = 2$$
A) $0.291 , - 2.291$
B) $2.291 , - 0.291$
C) $4.582 , - 0.582$
D) $1.577,0.423$

Quizplus · Accepted Answer

We can solve the equation by using the quadratic formula:

$$x = \frac{-(-6) \pm \sqrt{(-6)^2 - 4(3)(2)}}{2(3)} = \frac{6 \pm \sqrt{36-24}}{6} \approx \{2.291, -0.291\}$$

Therefore, the answer is choice B, which contains the two rounded solutions.
