    [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]
