    you would, if you didn't mess up :) (2m-5n)(2m-7n) =(2m-5n)3m - (2m-5n)7n =6m^2-15mn - 14mn+35n^2 =6m^2 -29mn +35n^2

    it's cool, especially when you multiply stuff like: (2m-5n+8k)(4m+6) How would you do that with FOIL ? :)

    yeah true but you can still do that with FOIL, and the box one looks complicated
