Incorrect. Recognize that $\displaystyle{{\left({x}+{5}\right)}}^{{2}}\usepackage{cmbright}\Huge\$ has a special product, since it is the square of a sum. Use the formula $\displaystyle{{\left({a}+{b}\right)}}^{{2}}={{a}}^{{2}}+{2}{a}{b}+{{b}}^{{2}}\usepackage{cmbright}\Huge\$ to find the first term.
