Answer 1

`\begin{gathered} \sqrt[]{3}\tan ^2x+\tan x=0 \\ \sqrt[]{3}\tan ^2x=-\tan x \\ \text{Dividing both sides by tan x} \\ \sqrt[]{3}\tan ^{}x=-1 \\ \tan x=\frac{1}{\sqrt[]{3}} \\ x=\tan ^(-1)\frac{1}{\sqrt[]{3}} \\ x=-30\text{ deg = -30 + 360 = 330} \\ 330\text{ degr = }(330\pi)/(360)=(11\pi)/(12) \\ x=-30\text{ deg = -30 + 180 = 150} \\ 150\text{ degr = }(150\pi)/(360)=(5\pi)/(12) \\ x\text{ = 0 is the trivial solution.} \\ \text{Therefore, x = }(11\pi)/(12),\text{ x =}(5\pi)/(12),x=0 \end{gathered}`
