You asked:
Evaluate the expression: \({\sqrt{x}}^{2} - 2 + \frac{1}{{x}^{2}}\)
MathBot Answer:
Evaluated
\(\displaystyle {\sqrt{x}}^{2} - 2 + \frac{1}{{x}^{2}} = x - 2 + \frac{1}{x^{2}} \)
Factored
\[{\sqrt{x}}^{2} - 2 + \frac{1}{{x}^{2}} = \frac{\left(x - 1\right) \left(x^{2} - x - 1\right)}{x^{2}}\]
