I was born in New York City and grew up in an apartment building ①there. My family, with Irish roots, lived on the top floor. People of German, Italian, and Puerto Rican backgrounds lived on different floors. When I climbed the stairs to our apartment, I often ran into people on the other floors. They said "Hi!" to me and sometimes offered me tea and sweets. I liked my neighbors and had nice chats with them. I gradually got interested in foreign cultures. Each apartment had an emergency exit. When I felt sad, I went through it and sat on the emergency stairs for a while. For me, the exit was like the hatch of a submarine. Outside, I often felt like I was in another world, a world of imagination.

不定詞の問題です。教えてください。書いているところは合っているか確認お願いします🙇

数学A途中式どこまで書けばいいですか？

（1）はなぜルートを外したのに（−5）になってるのでしょうか？教えてください

10 (1) (ア)(-5)=|-5|=5

絶対値の答えは絶対自然数なのになぜ答えが−√2＋3となる答えがあるのでしょうか？教えてください。

因数分解のこの問題の答えはなぜここで止まるとわかるのですか？

3 ①a²+ b² = (a+b) (a²- ab+ b²) 3 = (a+b)³ ( a + b² ) ³ + = a C 3 C² - 3ab (a+b+c) (a+b+c) { (a+b)-(a+b)c+c+ -3 ab(a+b+c) = (a+b+c) { +20b+/- ac-bc+c=zab} = (a+b+c) (Q²+b²+ c² -ab-ac-bc)

ここの問題全て違いがわからなくて詳しく教えてほしいです。なぜ正解なのかわからないです。

(1) 私はその物語を知っている。私は以前この本を読んだに違いない。 I remember the story.

＿なぜここは字数の1番低い文字で整理するのでしょうか？教えてください

(2) a³(b-c)+b³(c-a)+c³(a-b) =(b-c)a3-(63-c³)a+b3c-bc3 =(b-c)a³-(b-c)(b²+bc+c²)a+bc(b+c)(bc) =(b-c){a-(62+bc+c2a+bc(b+c)} =(b-c){(c-a)b2+c(c-a)b-a(c+a)(c-a)} <a について整理。 係数を因数分解。 共通因 数b-c が現れる。 { }内を次数の低い について整理。 共通因数 =(b-c)(c-a){b2+cb-a(c+a)} =(b-c)(c-a)(b-a){c+(b+α)} (vxk) - "(x+ c-aが現れる =(b-c)(c-a)(b-a)(a+b+c) +(x+x)) = =-(a-b) (b-c) (c-a) (a+b+c) (x+x+5)= これでも正解。 輪環の順に整理。

なぜここは共通因数があるのにくくらないんですか？

答 (1) a²(b+c)+b²(c+a)+c²(a+b)+3abc =(b+c)a²+(62+ c²+3bc)a+bc(b+c) ={a+(b+c)}{(b+c)a+bc} =(a+b+c)(ab+be+ca)
