    5x² - 39wx + 28w²

    Step-by-step explanation:

    Use the so-called "foil" method: multiply the first terms, the outer terms, the inner terms and the last terms:

    5x² - 35wx - 4wx + 28w²

    Combining the two middle terms, we get 5x² - 39wx + 28w²

    (5x^2) + (-35xw) + (-4wx) + (28w^2)

    Step-by-step explanation:

    (5x times x) + (5x times - 7w) + (-4w times x) + (-4w times - 7w)

    (5x^2) + (-35xw) + (-4wx) + (28w^2)
