Incorrect. Remember that polynomials in the form $\displaystyle{{a}}^{{2}}+{2}{a}{b}+{{b}}^{{2}}\usepackage{cmbright}\Huge\$ represent the square of a sum, and polynomials in the form $\displaystyle{{a}}^{{2}}-{2}{a}{b}+{{b}}^{{2}}\usepackage{cmbright}\Huge\$ represent the square of a difference. Can you identify those patterns within the polynomials above?
