Parabola, `P_1` has focus at `S(2,2)` and y-axis is its directrix. Parabola, `P_2` is confocal with `P_1` and its directrix is x-axis. Let `Q(x_1, y_1)` and `R(x_2, y_2)` be real points of intersection of parabolas `P_1a n dP_2dot` If the ratio `(R S)/(Q S)=a+bsqrt(b)` find `(a+b)` (given `x_2> x_1` and `a , b in N)dot`
