Simplified:

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

$$\begin{aligned}x^{2} - \frac{4}{x^{2}} + 2 x&=x^{2} + 2 x + \frac{-4}{x^{2}}\\&=\frac{x^{2} x^{2}}{x^{2}} + \frac{2 x x^{2}}{x^{2}} - \frac{4}{x^{2}}\\&=\frac{x^{3} \left(x + 2\right) - 4}{x^{2}}\end{aligned}$$

Factored:

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