Answer:
Let the term be equal to x
(p+q+x)/(p-q+x) = (p+q)^2/(p-q)^2
=> (p+q+x)/(p-q+x) = (p^2+q^2+2pq)/(p^2+q^2-2pq)
=> (p^2+q^2-2pq)(p+q+x) = (p^2+q^2+2pq)(p-q+x)
=> p^{3} + p^{2}q + p^{2}x + q^{2}p + q^{3} + q^{2}x - 2p^{2}q - 2pq^{2} - 2qpx = p^{3} - p^{2}q + p^{2}x + q^{2}p - q^{3} + q^{2}x + 2p^{2}q - 2pq^{2} + 2pqx
