Correct. Applying the Distributive Property, you can rewrite $\displaystyle{\left({x}+{1}\right)}{\left({2}{{x}}^{{2}}+{3}{x}+{1}\right)}\usepackage{cmbright}\Huge\$ as $\displaystyle{x}{\left({2}{{x}}^{{2}}+{3}{x}+{1}\right)}+{1}{\left({2}{{x}}^{{2}}+{3}{x}+{1}\right)}\usepackage{cmbright}\Huge\$ . This simplifies to $\displaystyle{2}{{x}}^{{3}}+{5}{{x}}^{{2}}+{4}{x}+{1}\usepackage{cmbright}\Huge\$ .
