I think the last term is qx^2
$${I}\:{think}\:{the}\:{last}\:{term}\:{is}\:{qx}^{\mathrm{2}} \\ $$

qy^2 −py^2   y^2 (q−p)
$${qy}^{\mathrm{2}} −{py}^{\mathrm{2}} \\ $$$${y}^{\mathrm{2}} \left({q}−{p}\right) \\ $$

p(x^2 −y^2 )+q(y^2 −x^2 )  =(x−y)(x+y)(p−q)
$${p}\left({x}^{\mathrm{2}} −{y}^{\mathrm{2}} \right)+{q}\left({y}^{\mathrm{2}} −{x}^{\mathrm{2}} \right) \\ $$$$=\left({x}−{y}\right)\left({x}+{y}\right)\left({p}−{q}\right) \\ $$
