Nghiệm của phương trình 2 sinx(cosx - 1) = căn 3 cos2x là: pi/3 + k2pi

A. $\frac{\mathrm{\pi }}{3}+k2\mathrm{\pi }, \mathrm{k}\in \mathrm{\mathbb{Z}} \mathrm{hoặc} \frac{4\mathrm{\pi }}{9}+\mathrm{k}2\frac{\mathrm{\pi }}{3}, \mathrm{k}\in \mathrm{\mathbb{Z}}$

B. $\frac{\mathrm{\pi }}{3}+k\mathrm{\pi }, \mathrm{k}\in \mathrm{\mathbb{Z}} \mathrm{hoặc} \frac{4\mathrm{\pi }}{9}+\mathrm{k}\frac{\mathrm{\pi }}{3}, \mathrm{k}\in \mathrm{\mathbb{Z}}$

C. $\frac{-\mathrm{\pi }}{3}+k2\mathrm{\pi }, \mathrm{k}\in \mathrm{\mathbb{Z}} \mathrm{hoặc} \frac{2\mathrm{\pi }}{9}+\mathrm{k}2\frac{\mathrm{\pi }}{3}, \mathrm{k}\in \mathrm{\mathbb{Z}}$

D. $\frac{-\mathrm{\pi }}{3}+k\mathrm{\pi }, \mathrm{k}\in \mathrm{\mathbb{Z}} \mathrm{hoặc} \frac{2\mathrm{\pi }}{9}+\mathrm{k}\frac{\mathrm{\pi }}{3}, \mathrm{k}\in \mathrm{\mathbb{Z}}$
