(2)でs=△ABC−(△ADF+△BED+△CFE)がなぜ1−3t(1−t)という式が出てくるのですか?途中式分からないので教えてください😭 △ABCは1である事はわかるので主に−3t(1−t)までの途中式教えてください

[2] あるクラスでディベートが行われています。 (1)~(3)はディベートの前半戦, (4)(5)は後半戦における発言の (1) 一部です。 ディベートの流れを意識しながら, 進行役の先生のセリフ が流れよく成り立つよう、下線に当てはまるものを選択肢から選び, 記号で答えなさい。 [思・判・表] (2) (教科書 P.88~89, P.92~95 参照) (3) (1) Teacher Are you ready to start our class debate? (4) Our topic is here on the board: "Digital books are better than paper books." (5) Raise your hand if you have a reason to support for this statement. (2) Student A: With an eReader, we have access to all of the books that we own. We can read many on the train. We can't carry many books with us every day. Teacher: (3) Student B Paper books don't use electricity. It's important that we use as little electricity as possible to prevent global warming. Teacher: (5点x5) (4) Teacher: Next, we will refute the other side's opinions. Say which opinion you are refuting, give your refutation, then give an example. (5) Student C They said that digital books are convenient, but I don't think it's a big advantage. We don't always need all of our books with us. Just one book is enough. Teacher: [選択肢] J. Good idea. "Good for the environment." 5. Great. "Digital books are convenient." 1. Let's start with the affirmative side. I. Very good. "Not a significant advantage." *. Let's start with the negative side.
