    I'm sorry to hear that, but I'm trying to teach you the FOIL method. Please stop me and ask any questions.

    Each letter in the word FOIL stands for one step in the method.

    The word "binomial" comes from the two parts: "bi" which means two because it has two terms like (a +b) and "nomial" which means name or just term.

    (−2x + 4y)(3x − 7y) multiply the First terms of the binomials (-2x)(3x) = -6x^2

    (-2x + 4y) is a binomial and (3x -7y) is a binomial, so the FOIL method works when you are multiplying two binomials. Recall each of -2x, 4y, 3x, and -7y are called terms, right?

    multiply the first term of each binomial by the last term of the other and add these products: "O" stands for Outer terms and "I" stands for inner terms

    The last letter in the word "FOIL" is L and it stands for multiply the Last terms of the binomials.
