`inte^x((x+2)/(x+4))^2dx`

int e^(x)((x+2)/(x+4))^(2)dx

If int e^(x)((x+2)/(x+4))^(2) dx = e^(x)((x-alpha)/(x+beta))+C where C is integration constant), then |beta - alpha| is equal to

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

int(x^2)/(x^4+5x^2+6)dx=

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

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

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

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