Identifying the Middle Term in Binomial Expansion

A system analyst is verifying a threshold calculation using the radical equation p1+1=p\sqrt{p - 1} + 1 = p. During the solution process, the analyst isolates the radical and squares both sides, resulting in the expression (p1)2(p - 1)^2. According to the Binomial Squares Pattern (ab)2=a22ab+b2(a - b)^2 = a^2 - 2ab + b^2, what is the specific middle term of the trinomial that results from expanding (p1)2(p - 1)^2?
