$x = - 2.766 \text{ or " + 1.266" }$ to 3 decimal places

If you need more detail about the calc go to my profile page and put a not on it!

#### Explanation:

$\frac{3}{2} = \frac{11 - 2 {m}^{2} - 4}{2 m}$

$6 m = 22 - 4 {m}^{2} - 8$

$4 {m}^{2} + 6 m - 14 = 0$

$\textcolor{b l u e}{\text{Attempt 4}}$

$x = \frac{- 6 \pm \sqrt{{6}^{2} - 4 \left(4\right) \left(- 14\right)}}{2 \left(4\right)}$

$x = \frac{- 6 \pm \sqrt{36 + 224}}{8}$

$x = \frac{- 6 \pm \sqrt{260}}{8}$

$x = \frac{- 6 \pm 2 \sqrt{65}}{8}$
