(1+z+z^2)^2 
19980910 

From A.R.: These questions deal with factoring. (1+z+z^2)^2 and (p^2pq+q^2)^2 I partially understand the second line which would be 1+z^2+z^4+2z+2z^2+2z^3 but I don't understand where the 2 comes from in the second half of that line. p.s.(^2 means squared or cubed etc.) Please help me out A.S.A.P.! I have a quiz on this tomorrow! Thankyou, A.R. Answered by Harley Weston.
