I mean this whole (5x - 7) - we can multiply it by the 3x and also by the 2 we get 3x (5x - 7) + 2 (5x - 7) and then this gives us 3x * 5x is going to be 15x^2 3x * -7 is going to be -21x then, remember this step we're just applying the distributive property again, so then we have 2 * 5x is just going to be 10x and then we have 2 * -7 is -14 so we actually got exactly the same result that we did when we applied FOlL and when you simplify it, you get this answer again.
