Step-by-step explanation:

We use the quadratic formula

$x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

$x = \frac{-\left(-7\right)+\sqrt{\left(-7\right)^2-4\cdot \:5\left(-18\right)}}{2\cdot \:5}$

= $\frac{7+\sqrt{409}}{10}$

$x = \frac{-\left(-7\right)-\sqrt{\left(-7\right)^2-4\cdot \:5\left(-18\right)}}{2\cdot \:5}$

= $\frac{7-\sqrt{409}}{10}$
