    4x times 4x equals 16x^2 (16x squared - little two after the x) 4x times 3y equals 12xy -3y times 4x equals -12xy -3y times 3y equals -9y^2 (-9y squared - little two after the y) So you get 16x^2 + 12xy - 12xy - 9y^2 Now you combine like terms... Which means +12xy combined with -12xy equals zero. So you are left with 16x^2 - 9y^2. Let me know if you have any problems figuring out what I'm saying! :)
