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

Value of int (x ^(2) + 1)/((x -1) (x-2)) dx is

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

int(3x^(2)+1)/(x(x^(2)+1))dx

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

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

int((x^(2)+x+1))/((x+2)(x+1)^(2))dx

(i) int((x^(2) - 1)/(x^(2) + 1))dx , (ii) int ((x^(6)- 1)/(x^(2) + 1))dx (iii) int ((x^(4))/(1+x^(2)))dx , (iv) int((x^(2))/(1+x^(2)))dx

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

"int(2x+1)/((x+1)(x+2)^(2))dx
