Incorrect. If the polynomial can be factored, the factorization will "look like" $\displaystyle{\left({3}{x}+{r}\right)}{\left({x}+{s}\right)}\usepackage{cmbright}\Huge\$ , where $\displaystyle{r}{s}=-{10}\usepackage{cmbright}\Huge\$ and $\displaystyle{r}+{3}{s}={1}\usepackage{cmbright}\Huge\$ . Can you find values for r and s that work?
