The solution
Detail solution
Given the inequality:
$$\left(x^{2} - 2 x\right) + 2 > 0$$
To solve this inequality, we must first solve the corresponding equation:
$$\left(x^{2} - 2 x\right) + 2 = 0$$
Solve:
$$y_{1} = 1 - 1 i$$
$$y_{2} = 1 + 1 i$$
Exclude the complex solutions:
This equation has no roots,
this inequality is executed for any x value or has no solutions
check it
subtitute random point x, for example
$$\left(x^{2} - 2 x\right) + 2 > 0$$
so the inequality has no solutions
