Correct. Divide each term in the polynomial by the monomial. The question mark stands for 3.

$\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}}}}=\frac{{{4}{{x}}^{{3}}}}{{3}}+{2}-\frac{{2}}{{{3}{x}}}\usepackage{cmbright}\Huge\$
