不定詞(いろいろな形/原形不定詞) Track 24-25 UNIT 5 Reading ARE *examination, 24 カザフスタン生まれの義足アスリート, ハインリッヒ・ポポフが自分の半生を振り返ります。 I was nine years old when my life changed completely. During an doctors found bone cancer in my left leg. (be / cut / needed / off / the leg/to). But I wasn't giving up; I wanted to do sports again. Desc Sports were always my passion, and, like many children, I wanted to be a 5 professional football player. But I realized this would not be possible and started training for track and field events. My new *prosthesis, an artificial leg, was a new beginning for me. テーマ スポーツ (100) I am often asked why I chose to be a *sprinter. The point is, I run because I'm missing a leg. In other words, although I lost my leg, I learned something very 10 important: Accept your challenge and try to ( 3 ) it. Everything can be an opportunity if you only realize that it is. Note I started my sports career in 2001. In 2004, I participated in the Paralympics in *Athens for the first time and won three *bronze medals in the 100 meter, 200 meter, and *long jump. At the 2012 Paralympics in London, I won gold in the 100 meter 15 sprint. G 25 prinodail It sounds so easy now, but it wasn't always like that.

線で囲ってある部分について質問です。 なぜ商が定数になるのですか?

112 第2章 高次方程式 Check 例題 54 剰余定理(2) 整式 P(x) を x2+x+1 で割ると余りはx+1, x-1 で割ると余りは 11のとき,P(x) を x-1 で割った余りを求めよ. (東京電機大改) STOLOM (1 %) ²0 [考え方 P(x) を2次式x+x+1で割った商をQ(x) とすると、余りはx+1. この商をさら にx-1で割った商をQ'(x), 余りを定数αとして, P(x) を考える. ここで,P(1)=11 となることから,定数aの値を求める. 解答 Focus P(x) を x2+x+1 で割った商をQ(x) とすると,余りは x+1 より, P(x)=(x2+x+1)Q(x)+x+1 ① さらに,Q(x) をx-1で割った商をQ'(x), 余りを定数 αとすると, Q(x)=(x-1)Q'(x)+α ..2 ②を①に代入すると, P(x)=(x2+x+1){(x-1)Q'(x)+α}+x+1 =(x-1)(x2+x+1)Q'(x)+α(x2+x+1)+x+1 =(x-1)Q'(x)+α(x2+x+1)+x+1 P(x) をx-1で割ると余りは11より, P(1)=11 したがって, ③より, P(1)=a(12+1+1)+1+1=11 よって, 求める余りは, a=3 3(x2+x+1)+x+1=3x²+4x+4 P=BQ+R 商のQをさらに割ってみる *** .....3 R(x)=a(x2+x+1)+x+1 ここで②① に代入してP(x) を考えてもよい. ...... 1次式で割ったとき の余りは定数 注> P(x) を x-1=(x-1)(x2+x+1) で割った商をQ(x), 余りをR(x) (2次以下)とす ると, 剰余の定理 P(x)=(x-1)(x2+x+1)Q(x)+R(x) ・・・・・① さらに,R(x) を x2+x+1 で割った商を定数aとすると,余りはx+1 より, ·②
