   [SOLVED] factorizing x^5y^2 + x^2y^5
   
   factorize:
   
   
   [tex]x^5y^2 + x^2y^5[/tex]
   
   
   
   3. The attempt at a solution
   
   
   I have attempted to use difference of two squares by re-arranging as:
   
   
   [tex]x^5y^2 + y^5x^2[/tex]
   
   but this doesn't get me anywhere

   Take out common things.
   [tex]x^2y^2(x^3+y^3)[/tex]
   
   Now use the expansion for [tex](x^3+y^3)[/tex]
