(s^2+4) will give 2j as one of the pole mentioned by Ahmed and (S^2+1) will j as pole
j=√(-1) --------> formula.
j=√(-1) --------> formula.

[(s^2+4)(S^2+1) how we obtained these 4 poles?

The transfer functio is (s+2)/[(s^2+4)(S^2+1)(S+1)].
The magnitude is 2/4=0.5 ;when put w=0.
The angle is tan^-1 (w/2) - tan^-1(w)=0 ; when put w=0.
The magnitude is 2/4=0.5 ;when put w=0.
The angle is tan^-1 (w/2) - tan^-1(w)=0 ; when put w=0.

I don't understand that how to join j1 with zeros and pole please explain in detail.

Poles are -1, -j, j, -2j, 2j.
Zero is -2.
Zero is -2.
