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

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

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

What is int(2x^2+3)/((x^2-1)(x^2+4))dx?

If int(2x^2+3)/((x^2-1)(x^2+4))dx=alog((x-1)/(x+1))+btan^(- 1) (x/2)+C then the values of a and b are respectively (A) 1/2,1/2 (B) 1,1 (C) 1/2,1 (D) None

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

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

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

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