    Factoring a single Binomial with two variables

    So, I'm having a problem with some really basic factoring, embarasing really.
    my problem is this, I can't seen to factor a binomial with two variables, such as this


    20xy^(3) +25x^(6)y^(9)

    like i said, pretty basic but im having trouble with it.(confused)

    You need to find the greatest common factor of 20xy^3 and 25x^6y^9. Break it down by calculating the least power of x between the two, the least power of y between the two, and the greatest common factor of 20 and 25.

    Least power of x: 1
    Least power of y: 3
    GCF of 20 and 25: 5

    Therefore, you can factor out 5xy^3, yielding 5xy^3(4 + 5x^5y^6).
