($x^{2}$+1)/($x^{2}$-4)
You asked:
Evaluate the expression: \(\frac{{x}^{2} + 1}{{x}^{2} - 4}\)
MathBot Answer:
Evaluated
\(\displaystyle \frac{{x}^{2} + 1}{{x}^{2} - 4} = \frac{x^{2} + 1}{x^{2} - 4} \)
Expanded
\[\frac{{x}^{2} + 1}{{x}^{2} - 4} = \frac{x^{2}}{x^{2} - 4} + \frac{1}{x^{2} - 4}\]
Factored
\[\frac{{x}^{2} + 1}{{x}^{2} - 4} = \frac{x^{2} + 1}{\left(x - 2\right) \left(x + 2\right)}\]
