The parabola with equation $p(x) = ax^2+bx+c$ and vertex $(h,k)$ is reflected about the line $y=k$. This results in the parabola with equation $q(x) = dx^2+ex+f$. Find the value of $a+b+c+d+e+f$. The original answer is in the form of $k*h$, please give the value of $k$.

Let's think step by step and output the final answer within \boxed{}.
