Hello, I need to find the pole points and zero points of the following equation GH= 3(p+2) / (p+8 )*(p²+8p+32) For zero points you get 2 and pole points are 8, 4+j4, 4j4 (the p+2 in the numerator determines the zero points and the denominator determines the pole points) However, I can't figure out how you get those complex values. In order to get the pole points you need to have a p value, not p² (I think at least). So you'd have to convert it. J is a complex number > sqroot of 1 Here is a screenshot of what I mean My current (flawed) theory is that you need to reduce p² to p by apply that p! rule, meaning you change (p²+8p+32) into (2p+8 ) > 2(p+4) However, I can't figure out how you end up with the complex number out of this.

The complex pole points are simply the roots of .
