If alpha,beta(beta>alpha), are the root...

If `alpha,beta(beta>alpha),` are the roots of `g(x)=a x^2+b x+c=0` and `f(x)` is an even function, then `int_alpha^betae^(f((g(x))/(x-alpha)))/(e^(f((g(x))/(x-alpha)))+e^(f((g(x))/(x-beta))))=` (a)`|b/(2a)|` (b) `(sqrt(b^2-4a c))/(|2a|)` (c)`|b/a|` (d) none of these
