Incorrect. This equation can be factored as $\displaystyle{2}{\left({x}+{1}\right)}{\left({x}+{1}\right)}={0}\usepackage{cmbright}\Huge\$ . Using the zero product property, either $\displaystyle{2}={0}\usepackage{cmbright}\Huge\$ , $\displaystyle{x}+{1}={0}\usepackage{cmbright}\Huge\$ or $\displaystyle{x}+{1}={0}\usepackage{cmbright}\Huge\$ . What can you conclude from each of these possibilities?
