Here is your answer
The equation is
${x}^{2} - 4 \sqrt{3} x + 3$
Here
a = 1
b = - 4√3
c = 3

If alpha and beta are the roots
so
Sum of roots = -b/a
$\alpha + \beta = - \frac{( - 4 \sqrt{3}) }{1} \\ \alpha + \beta = 4 \sqrt{3}$
Product of roots = c/a
$\alpha \beta = \frac{3}{1} \\ \alpha \beta = 3$
Now we find the value of

$\alpha + \beta - \alpha \beta \\ = 4 \sqrt{3} - 3$
