Incorrect. If you use the letters a, b, c, and d to represent each term, you know that $\displaystyle{\left({a}+{b}\right)}{\left({c}+{d}\right)}={a}{\left({c}+{d}\right)}+{b}{\left({c}+{d}\right)}={a}{c}+{a}{d}+{b}{c}+{b}{d}\usepackage{cmbright}\Huge\$ . If you use this strategy in the first problem, you find that $\displaystyle{\left({2}{y}+{9}\right)}{\left({13}{y}-{4}\right)}={26}{{y}}^{{2}}-{8}{y}+{117}{y}-{36}\usepackage{cmbright}\Huge\$ . Collect like terms and see which one it matches. Then, repeat the process for the other two problems.
