Answer:

oh dear friend I don't know your answer

Answer 2

By completing square method

$4 {x}^{2} + 4 \sqrt{3} x + 3 = 0$

$dividing \: by \: 4$

${x}^{2} + \sqrt{3} x + \frac{3}{4} = 0$

${x}^{2} + \sqrt{3} x = - \frac{3}{4}$

$make \: perfect \: square$

${x}^{2} + \sqrt{3} x + {( \frac{ \sqrt{3} }{2} )}^{2} = - \frac{3}{4} + \frac{3 }{4}$

$( {x + \frac{ \sqrt{3} }{2} )}^{2} = 0$

$( {x + \frac{ \sqrt{3} }{2} )} = 0$

$x = - \frac{ \sqrt{3} }{2}$
