Incorrect. You know that $\displaystyle{a}={2},{b}={4},\usepackage{cmbright}\Huge\$ and $\displaystyle{c}={2}.\usepackage{cmbright}\Huge\$ Substitute those values in for the variables in the discriminant, $\displaystyle{{b}}^{{2}}-{4}{a}{c}\usepackage{cmbright}\Huge\$ . Use that information to determine how many solutions the equation has.
