Evaluate: int(2+x+x^2)/(x^2(2+x))+(2x-1)...

Evaluate: `int(2+x+x^2)/(x^2(2+x))+(2x-1)/((x+1)^2)\ dx`

Text Solution

Verified by Experts

`int((2+x+x^2)/(x^2(2+x))+(2x-1)/((x+1)^2))\ dx`

`=int(1)/(x^2)dx+int(1)/(2+x)dx+int(2(x+1)-3)/((x+1)^2)\ dx`

`=int(1)/(x^2)dx+int(1)/(2+x)dx+int(2(x+1))/((x+1)^2)dx-int(3)/((x+1)^2)\ dx`

`=(-1)/(x)+ln(2+x)+2ln(x+1)+(3)/(x+1)+C`
