They believe that they would be ignored if representation was based on population while large states, because they will not have the same advantages that the big states have.
Answer: p^2 + 4q^2 + r^2 + 4pq + 4qr + 2pr
Explanation:
We need to expand (p+2q+r)^2
We know that (x+y+z) ^2 = x^2 + y^2 + z^2 + 2xy + 2yz + 2xz
Here x = p,y = 2q and z = r
Therefore (p+2q+r)^2 = (p)^2 + (2q)^2 + (r)^2 + 2(p)(2q) + 2(2q)(r) + 2(p)(r)
= p^2 + 4q^2 + r^2 + 4pq + 4qr + 2pr
The game is said to have originated from the Three Kingdoms period of Korea when the three kingdoms were fighting for land. In this version, the area which the offensive team has to reach while passing the defensive team is called the "unification area". ( hope this helps !)
