Answer 1

we know that quadratic polynomial

x²-(sum of roots)x+(product of roots )

${x}^{2} - ( - 2 \sqrt{3} - \frac{ \sqrt{3} }{2} )x + ( 2 \sqrt{3} \times \frac{ \sqrt{3} }{2} ) \\ {x}^{2} - ( \frac{ - 4 \sqrt{3} - \sqrt{3} }{2} )x + 3 \\ {x}^{2} - ( \frac{ - 5 \sqrt{3} }{2} )x + 3 \\ {x}^{2} + \frac{5 \sqrt{3} }{2} x + 3$
