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

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

I= int dx/(x^2+x+1)^2=Atan^-1((2x+1)/(sqrt3))+B(2x+1)/(x^2+x+1) then Find the value of A and B

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

int(dx)/(2x^(2)+x-1) is equal to

What is int(dx)/(2x^(2)-2x+1) equal to ?

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

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

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

If int (dx)/((x^(2)+a^(2))^(2))=(1)/(ka^(2)){(x)/(x^(2)+a^(2))+(1)/(a) tan^(-1). (x)/(a)}+C . Then the value of k, is
