find total impedance of a circuit with R1 and L in parallel with R2.

circuit looks like this (but with R2 instead of C): http://wpcontent.answcdn.com/wikipe...rallel.svg/160px-RL_series_C_parallel.svg.png

2. Relevant equations

formula for two components in parallel: [tex]Z_T = Z_1 Z_2/(Z1 + Z_2)[/tex]

3. The attempt at a solution

question is, can I first combine the two resistors in parallel, then add the inductor in series? Or must I do the inductor and R1 together, in parallel with R2? So, eith er R1||R2 + Z_L or (R1+Z_L)||R2 ?

I'm assuming the last one?
