# resistor values of a 4th order bessel high pass filter

I have a question about cascading the 2nd order bessel high pass filter to form a 4th order bessel high pass filter, I have an equation to solve for R1 and R2, will the same equation be used to solve for R3 and R4 of the cascaded 2nd order bessel high pass filter?

$s^4 + 6s^3 + 15s^2 + 18s + 9$
