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

int e^(x)[((x+3))/((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

" 4.Evaluate: "int e^(x)((x-1)/(x^(2)))dx

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

int e^(x)((x+2)/(x+4))^(2)dx=(f(x)e^(x))/(x+4)+c then the sum f(x)+f^(2)(x)+f^(3)(x)+....oo at x=(1)/(2)

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