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

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

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

int((2x^(2)+3)dx)/((x^(2)-1)(x^(2)+4))=

int((2x^(2)+1)dx)/(x^(4)+3x^(2)+4)

Evaluate int (x^2 dx)/((x^2 +1)(x^2 +4))

If int((2x^(2)+1)dx)/((x^(2)-4)(x^(2)-1))=log[((x+1)/(x-1))^(a)((x-2)/(x+2))^(b)]+c , then the values of a and b are respectively

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