Correct. Applying the quadratic formula gives the equation $\displaystyle{x}=\frac{{-{\left(-{7}\right)}\pm\sqrt{{{{\left(-{7}\right)}}^{{2}}-{4}{\left({5}\right)}{\left(-{3}\right)}}}}}{{{2}{\left({5}\right)}}}=\frac{{{7}\pm\sqrt{{{49}+{60}}}}}{{{10}}}=\frac{{{7}\pm\sqrt{{{109}}}}}{{10}}\usepackage{cmbright}\Huge\$ . This means $\displaystyle{x}=\frac{{{7}+\sqrt{{{109}}}}}{{10}}\usepackage{cmbright}\Huge\$ and $\displaystyle{x}=\frac{{{7}-\sqrt{{{109}}}}}{{10}}\usepackage{cmbright}\Huge\$ .
