Answer:

x = \frac{4\pi }{9},\frac{10\pi }{9}

Step-by-step explanation:

Given equation is,

\sqrt{3}\text{tan}(\frac{2x}{3})+1=0

By solving this equation,

\text{tan}(\frac{2x}{3})=-\frac{1}{\sqrt{3}}

x=\frac{2}{3}\times \text{tan}^{-1}(-\frac{1}{\sqrt{3}}) [tangent of any angle is negative in IInd and IVth quadrants]

x = \frac{2}{3}\times (\frac{2\pi }{3}), \frac{2}{3}\times (\frac{5\pi}{3})

x = \frac{4\pi }{9},\frac{10\pi }{9}

Therefore, value of x in the interval of [0, 2π] are \frac{4\pi }{9},\frac{10\pi }{9}.
