Incorrect. Multiply each term in the first polynomial by each term in the second polynomial. To do this, apply the Distributive Property: $\displaystyle{{a}}^{{2}}{\left({2}{{a}}^{{2}}-{4}{a}+{3}\right)}+{5}{a}{\left({2}{{a}}^{{2}}-{4}{a}+{3}\right)}-{1}{\left({2}{{a}}^{{2}}-{4}{a}+{3}\right)}\usepackage{cmbright}\Huge\$ . Then multiply and combine like terms.
