Then we do that outside terms, so that's going to be the 3x times the -7 so this is going to be plus 3x times -7 then we want to do the inside terms we want to do the things in green. so that's the 2 and the 5x so that's plus 2*5x and then we want to do the last terms which are 2 and -7 so plus 2 times -7 and we end up getting 3x * 5x is 15x^2 plus, or I should say minus because there's going to be a negative sign here so 3x * (-7) is -21x then we have 2 * 5x is plus 10x and then 2 * (-7) is -14 now it's minus 14 and we can these two middle terms together if we have -21x and we add 10x to that that gives us -11x and then these other terms over here we have 15x^2-11x-14 so we just used FOlL what I want to do is show you that this is the same as using the distributive property twice so if we have, I'll rewrite the problem (3x + 2)(5x - 7) what we can do is distribute the (5x - 7) we can multiply that by the 3x and we can also multiply that -
