Incorrect. Divide each term in the polynomial by the monomial.

$\displaystyle\frac{{{8}{{x}}^{{5}}+{12}{{x}}^{{2}}-{4}{x}}}{{{6}{{x}}^{{2}}}}=\frac{{{8}{{x}}^{{5}}}}{{{6}{{x}}^{{2}}}}+\frac{{{12}{{x}}^{{2}}}}{{{6}{{x}}^{{2}}}}-\frac{{{4}{x}}}{{{6}{{x}}^{{2}}}}\usepackage{cmbright}\Huge\$

The correct answer is 3.
