Find the product. Use the FOIL method. -(x + 9y)(x - 3y) A) x + 6xy - 27y B) x² + 6xy + 6y² C) x² + 6xy - 27y² D) x² + 3xy - 27y²

Using the FOIL method, we multiply the first terms (x*x = x^2), the outer terms (x*(-3y) = -3xy), the inner terms (9y*x = 9xy), and the last terms (9y*(-3y) = -27y^2). Adding these together, we get x^2 + 6xy - 27y^2, which matches choice C.
