Incorrect. Remember to distribute the $\displaystyle{3}{{x}}^{{2}}\usepackage{cmbright}\Huge\$ to all three terms within parentheses. Multiply the coefficients first, and then multiply the variable terms. Recall that the Distributive Property states that $\displaystyle{a}{\left({b}+{c}\right)}={a}{b}+{a}{c}\usepackage{cmbright}\Huge\$ .
