How do you 1/(n*(n+1)*(n+2)) in partial fractions?
The solution
You have entered
[src]
1 ----------------- n*(n + 1)*(n + 2)
$$\frac{1}{n \left(n + 1\right) \left(n + 2\right)}$$
1/((n*(n + 1))*(n + 2))
Fraction decomposition
[src]
1/(2*n) + 1/(2*(2 + n)) - 1/(1 + n)
$$\frac{1}{2 \left(n + 2\right)} - \frac{1}{n + 1} + \frac{1}{2 n}$$
1 1 1 --- + --------- - ----- 2*n 2*(2 + n) 1 + n
Common denominator
[src]
1 --------------- 3 2 n + 2*n + 3*n
$$\frac{1}{n^{3} + 3 n^{2} + 2 n}$$
1/(n^3 + 2*n + 3*n^2)
