Answer...

 \sf \:  {pq}^{4}  - p {(p - q)}^{4}  \\  \\  \sf = p[ {q}^{4}  -  {(p - q)}^{4}] \\  \\  \sf = p[ {q}^{2}  +  {(p - q)}^{2}] [ {q}^{2}  -  {(p - q)}^{2} ] \\  \\  \sf = p[ {p}^{2} +   {2q}^{2}  - 2pq](q + p - q)(q + p - q) \\  \\  \sf = p({p}^{2}  +  {2q}^{2}  - 2pq)\: p(2q - p) \\  \\  \sf = p(  {p}^{2}  +  {2q}^{2}  - 2pq) \: (2q - p)
