Incorrect. First, factor 4 out of each term using the distributive property: $\displaystyle{4}{{x}}^{{2}}+{24}{x}+{36}={4}{\left({{x}}^{{2}}+{6}{x}+{9}\right)}\usepackage{cmbright}\Huge\$ . If $\displaystyle{{x}}^{{2}}+{6}{x}+{9}\usepackage{cmbright}\Huge\$ is a perfect square trinomial, what are its factors?
