Incorrect. The first step in factoring $\displaystyle{a}{{x}}^{{2}}+{b}{x}+{c}\usepackage{cmbright}\Huge\$ is to rewrite the $\displaystyle{b}{x}\usepackage{cmbright}\Huge\$ as $\displaystyle{r}{x}+{s}{x}\usepackage{cmbright}\Huge\$ , where $\displaystyle{r}+{s}={b}\usepackage{cmbright}\Huge\$ , and $\displaystyle{r}{s}={a}{c}\usepackage{cmbright}\Huge\$ . Then group the terms and factor out the common binomial factor.
