赤線の部分、どうしてwhoが接続詞ではなくて 節は名詞か形容詞なのですか？

33 関係代名詞は 「接着代名詞」なり 次の英文を訳しなさい Some people may believe that gold or jewels are important treasures, but there are other treasures that are far more important. They are our memories.

数2の方程式の問題なのですが、a.bの組み合わせが2.1と-2.3となる理由がわからないです。なぜその組み合わせになるのでしょうか。

以上か xの多項式P(x)=ax+bx+abx²-(a+36-4)x-(3a-2)がx2-1で割り切れるような定数 α, b の値の組を求めよ。 また, 求めた α, b の値の組に対し, P(x) を実数の範囲で因数分解せよ。 [類 駒澤大 ] ←x-1=(x+1)(x-1) EX ③40 P(x)がx2-1で割り切れるための条件は P(1) = 0 P(−1)=0\ P(1)=a+b+àb-(a+36-4)-(3a-2)=ab-3a-26+6 =a(b-3)-2(b-3)=(a-2) (6-3)* P(1) = 0 から よって P(-1) = 0 から ゆえに よって, 求める組 (α, b) は (a,b)=(2,1) のとき P(1)=P(−1)=0 であるから ② P(-1)=a-b+ab+(a+3b-4)-(3a-2)=ab-a+2b-2 =α(b-1)+206-1)=(a+2)(b-1) (a-2)(b-3)=0 α=2 またはb=3 2-6-20+6=0 a=-2 またはb=1 (a+2)(b-1)=0 71 (a,b)=(2,1), (-2,3) P(x)=2x^+x3+2x2-x-4 P(x)=(x+1)(x-1)(2x²+x+4) ......
