Answer
$$3x^3 - 2x + 6$$
Work Step by Step
Taking a look at the numerator of this rational expression, we see that the factor $6x$ is common to all three terms, so $6x$ is called the greatest common factor. We can simplify this expression by factoring out the greatest common factor to get:
$$\frac{6x(3x^3 - 2x + 6)}{6x}$$
Since we have $6x$ in both the numerator and denominator, they cancel each other out. We now have:
$$3x^3 - 2x + 6$$
