If $x^{2/3} - 7x^{1/3} + 10 = 0,$ then $x = \dots$

If $\alpha$ and $\beta$ $(\alpha > \beta)$ are the multiple roots of the equation $4x^4 + 4x^3 - 23x^2 - 12x + 36 = 0$,then $2\alpha - \beta = $

Consider the following two statements:
$I$. Any pair of consistent linear equations in two variables must have a unique solution.
$II$. There do not exist two consecutive integers,the sum of whose squares is $365$.
Then,

If the equation $x^4+7x^3+18x^2+20x+8=0$ has a repeated root,then that repeated root is

The quadratic equation whose one root is $2 - \sqrt{3}$ will be:

The number of real solutions of the equation $3(x^2 + \frac{1}{x^2}) - 2(x + \frac{1}{x}) + 5 = 0$ is:
