O.K., so you just use the relation: a(p)a+(q) = [a(p),a+(q)] + a+(q)a(p) for each case. Also can I just clarify that in the answer when it says: |qi-1> if i=1, is that just ignored? I' learning form these notes: http://www.hep.man.ac.uk/u/pilaftsi/QFT/qft.pdf With the aide...

I'm trying to show: a(p)|q1,q2,...,qN> = \sumNi=1(2pi)32Ep\delta(3)(p-qi)x|qi,...,qi-1,qi+1,...,qN> I'm pretty sure you have to turn the ket into a series of creation operators acting on the vacuum |0>, but then not sure what relations need to be invoked for it to be clear. Any help...
