(3x^2+2x+1)/(x^3-1)-(1-x)/(x^2+x+1)-2/(x-1)
You asked:
Evaluate the expression: \(\frac{3 \cdot {x}^{2} + 2 x + 1}{{x}^{3} - 1} - \frac{1 - x}{{x}^{2} + x + 1} - \frac{2}{x - 1}\)
MathBot Answer:
Evaluated
\(\displaystyle \frac{3 \cdot {x}^{2} + 2 x + 1}{{x}^{3} - 1} - \frac{1 - x}{{x}^{2} + x + 1} - \frac{2}{x - 1} = - \frac{1 - x}{x^{2} + x + 1} - \frac{2}{x - 1} + \frac{3 x^{2} + 2 x + 1}{x^{3} - 1} \)
Expanded
\[\frac{3 \cdot {x}^{2} + 2 x + 1}{{x}^{3} - 1} - \frac{1 - x}{{x}^{2} + x + 1} - \frac{2}{x - 1} = \frac{3 x^{2}}{x^{3} - 1} + \frac{x}{x^{2} + x + 1} + \frac{2 x}{x^{3} - 1} - \frac{1}{x^{2} + x + 1} - \frac{2}{x - 1} + \frac{1}{x^{3} - 1}\]
Factored
\[\frac{3 \cdot {x}^{2} + 2 x + 1}{{x}^{3} - 1} - \frac{1 - x}{{x}^{2} + x + 1} - \frac{2}{x - 1} = \frac{2 x}{x^{2} + x + 1}\]
