    looking backwards it seems like you have in that thinking that -4(2) = -24

    this is the problem: \[\frac{ x + \frac{ 5 }{ x } }{ 1+\frac{ 6 }{ x } }=4x\]

    \[\frac{-24 \pm 2 \sqrt{159}}{6}= \frac{\frac{-24}{2} \pm \frac{2 \sqrt{159}}{2}}{\frac{6}{2}} \\ \\ =\frac{-12 \pm \sqrt{159}}{3}\]

    in the end when you divided -24 by 2 you wrote -4 this is not true

    \[\frac{-24 \pm 2 \sqrt{159}}{6} \\ \text{ you can separate the fraction } \\ \\ \frac{-24}{6} \pm \frac{2 \sqrt{159}}{6} \\ -4 \pm \frac{\sqrt{159}}{3}\]

    Look at your last step, the solution. Now look one step up.

    -24 and 6 simplify to -12 and 3, not -4 and 3

    You made a small mistake in the very last step.

    \(\dfrac{-24 \pm 2\sqrt{159} }{6} = \dfrac{\cancel 2 (-12 \pm \sqrt{159})}{\cancel 2(3)}\)

    just curious so this didn't make any sense: \[\frac{-24 \pm 2 \sqrt{159}}{6}= \frac{\frac{-24}{2} \pm \frac{2 \sqrt{159}}{2}}{\frac{6}{2}} \\ \\ =\frac{-12 \pm \sqrt{159}}{3}\] ?
