#### Answer

$$2x^4 - x^3 + 3x + 9$$

#### Work Step by Step

Looking at the numerator of this fraction, we see that we can factor out a $3x$ from all terms. Let us do that first to simplify the fraction a little:
$$\frac{3x(2x^4 - x^3 + 3x + 9)}{3x}$$
We see that the $3x$ factor in the numerator and denominator cancel each other out, so we are left with:
$$2x^4 - x^3 + 3x + 9$$
