Question

Find the product of the binominals using the appropriate special product (difference of two squares, square of a binominal sum, or square of a binominal difference)
(3x+4y)(3x-4y)

Answer 1

9x^2 -16y^2

Answer 2

You could also just FOIL it (distribute)

Answer 3

Or you could notice that there are two 3x and two 4x and each binomial has a plus or minus. That indicates difference of squares....so you simply multply the 3x's together and the 4x's together and put a minus sign between their products.
