Pay attention to the negative sign in $\displaystyle-{\left({10}{{x}}^{{3}}+\frac{{1}}{{3}}{{x}}^{{2}}+{x}\right)}\usepackage{cmbright}\Huge\$ . This can also be written as $\displaystyle{\left(-{1}\right)}{\left({10}{{x}}^{{3}}+\frac{{1}}{{3}}{{x}}^{{2}}+{x}\right)}\usepackage{cmbright}\Huge\$ . How would you distribute the $\displaystyle-{1}\usepackage{cmbright}\Huge\$ ?
