To solve this equation, let us apply Quadratic formula
![2{x}^{2} -\sqrt{3}x + 1= 0 \\ \\ a = 2\\ \\ b = -\sqrt{3} \\ \\ c = 1 \\ \\ x_{1,2} = \frac{ - b ± \sqrt{ {b}^{2} - 4ac} }{2a} \\ \\ x_{1,2} = \frac{ \sqrt{3} ± \sqrt{ {(-\sqrt{3})}^{2} - 4(2)(1)} }{2 \times 2} \\ \\ x_{1,2} = \frac{ \sqrt{3} ± \sqrt{ 3 - 8} }{4} \\ \\ x_{1,2} = \frac{ \sqrt{3}±\sqrt{ -5} }{4} \\ \\ \\ x_{1,2} = \frac{ \sqrt{3} ± i\sqrt{5}}{4} \\ \\ x_{1} = \frac{ \sqrt{3} + i\sqrt{5}}{4} \\ \\ x_{2} = \frac{ \sqrt{3} - i\sqrt{5}}{4} \\ \\ 2{x}^{2} -\sqrt{3}x + 1= 0 \\ \\ a = 2\\ \\ b = -\sqrt{3} \\ \\ c = 1 \\ \\ x_{1,2} = \frac{ - b ± \sqrt{ {b}^{2} - 4ac} }{2a} \\ \\ x_{1,2} = \frac{ \sqrt{3} ± \sqrt{ {(-\sqrt{3})}^{2} - 4(2)(1)} }{2 \times 2} \\ \\ x_{1,2} = \frac{ \sqrt{3} ± \sqrt{ 3 - 8} }{4} \\ \\ x_{1,2} = \frac{ \sqrt{3}±\sqrt{ -5} }{4} \\ \\ \\ x_{1,2} = \frac{ \sqrt{3} ± i\sqrt{5}}{4} \\ \\ x_{1} = \frac{ \sqrt{3} + i\sqrt{5}}{4} \\ \\ x_{2} = \frac{ \sqrt{3} - i\sqrt{5}}{4} \\ \\](https://tex.z-dn.net/?f=2%7Bx%7D%5E%7B2%7D+-%5Csqrt%7B3%7Dx+%2B+1%3D+0+%5C%5C+%5C%5C+a+%3D+2%5C%5C+%5C%5C+b+%3D+-%5Csqrt%7B3%7D+%5C%5C+%5C%5C+c+%3D+1+%5C%5C+%5C%5C+x_%7B1%2C2%7D+%3D+%5Cfrac%7B+-+b+%C2%B1+%5Csqrt%7B+%7Bb%7D%5E%7B2%7D+-+4ac%7D+%7D%7B2a%7D+%5C%5C+%5C%5C+x_%7B1%2C2%7D+%3D+%5Cfrac%7B+%5Csqrt%7B3%7D+%C2%B1+%5Csqrt%7B+%7B%28-%5Csqrt%7B3%7D%29%7D%5E%7B2%7D+-+4%282%29%281%29%7D+%7D%7B2+%5Ctimes+2%7D+%5C%5C+%5C%5C+x_%7B1%2C2%7D+%3D+%5Cfrac%7B+%5Csqrt%7B3%7D+%C2%B1+%5Csqrt%7B+3+-+8%7D+%7D%7B4%7D+%5C%5C+%5C%5C+x_%7B1%2C2%7D+%3D+%5Cfrac%7B+%5Csqrt%7B3%7D%C2%B1%5Csqrt%7B+-5%7D+%7D%7B4%7D+%5C%5C+%5C%5C+%5C%5C+x_%7B1%2C2%7D+%3D+%5Cfrac%7B+%5Csqrt%7B3%7D+%C2%B1+i%5Csqrt%7B5%7D%7D%7B4%7D+%5C%5C+%5C%5C+x_%7B1%7D+%3D+%5Cfrac%7B+%5Csqrt%7B3%7D+%2B+i%5Csqrt%7B5%7D%7D%7B4%7D+%5C%5C+%5C%5C+x_%7B2%7D+%3D+%5Cfrac%7B+%5Csqrt%7B3%7D+-+i%5Csqrt%7B5%7D%7D%7B4%7D+%5C%5C+%5C%5C+)
