Incorrect. Because $\displaystyle{c}={9}\usepackage{cmbright}\Huge\$ , the constant term will be 9. Rewrite the equation so that the right side is equal to 0. Then the left side will have the term 9. The value of a is then the coefficient of the $\displaystyle{{x}}^{{2}}\usepackage{cmbright}\Huge\$ term. The correct answer is 8.
