x-2/x+2-2x+20/x^2+4
You asked:
Evaluate the expression: \(x - \frac{2}{x} + 2 - 2 x + \frac{20}{{x}^{2}} + 4\)
MathBot Answer:
Evaluated
\(\displaystyle x - \frac{2}{x} + 2 - 2 x + \frac{20}{{x}^{2}} + 4 = - x + 6 - \frac{2}{x} + \frac{20}{x^{2}} \)
Factored
\[x - \frac{2}{x} + 2 - 2 x + \frac{20}{{x}^{2}} + 4 = - \frac{x^{3} - 6 x^{2} + 2 x - 20}{x^{2}}\]
