Best ResponseYou've already chosen the best response.1If I had to pick one, I'd say Square of Binomial. Binomial means two terms. You have two terms. Then you're squaring them

Best ResponseYou've already chosen the best response.0I'm assuming you meant \[(20+5)^{2} = 25^{2}\] If so, the answer is none of them. All you are using is the fact that 20+5 =25
