これの答えとそうなった理由教えて欲しいです

5 次の英文を読んで、後の問いに答えよ。 In the "New England winter of 1891, it was too cold to "exercise outside. James Naismith, a Canadian college teacher, wanted to give his students a game to play inside. He tied two fruit baskets to the walls of the school's gym. Then, he gave the young men a soccer ball to throw into the baskets. At first, the students got too excited at the new game, and they began hurting each other. So James "created some rules. For example, he said that the players could not push or hit each other. He also made another important change Because he was tired of taking the ball out of the baskets after every score, he cut holes in the bottom of the baskets. Then he made a list of 13 simple rules and called the new game "basket ball." James shared the rules with other teachers. Basketball soon became popular in North America because it was fun, easy to learn, and could be played anywhere. Both boys' and girls' basketball teams began playing all over America and Canada. Basketball has become one of the world's most popular sports, but even now the 13 rules from 1891 are part of the game.

(1)が解説を見たのですが分かりませんでした。 教えて欲しいです🙇‍♀️

74 FUN 77 高次方程式の解の個数 方程式(a+1)x+3a-2a=0 について,次の問いに答えよ。 類 立教大 大 (2) 重解をもつようにaの値を定めよ。 (1) 異なる3つの実数解をもつように, α の値の範囲を定めよ。 解 (1) P(z)=(a+1)x+3ax-2a とおくと P(1)=1-(a+1)+3a-2a=00 (x− 1)(x²-ax+2a)=0 x-1=0 ①, x-ax+2a=0 ......2 ②① x = 1 以外の異なる2つの実数解をも てばよいから,②の判別式は D=a²-8a= a(a−8)>0 a<0, 8<a <>#38+1(8+0) — ³x 1-α+2a=0 より α=-10=8+(8+) よって, a<-1, -1 <a < 0, 8 <a (2) ②重解をもつとき D=0 より a=0,8 ②がx=1 を解にもつとき α = -1- よって, α=-10,8 アドバイス - fx=(x)¶ (s) また,②がx=1 を解にもつとき②にx=1 を代入して ②がx=1 を解をもつと きのαの値を求め、それ を除く。 ....... ◆定数項 24の約数を代入 して,因数を見つける。 る。 VISS= 高次方程式の解の個数 d+xa-xS ()() = (8-1)(S+1)(1-x)= (x-1)²(x+2)=0 となる。 ・3次以上の方程式では,重解や異なる解をもつ場合の考え方で注意しなくてはな らないことがある。 例えば, (40=(0)4. (x-a)(x²+bx+c)=0 £x=a=0 ²x²+bx+c=0> が同じ解をもつことがありうる。こ M だから x2+bx+c=0が異なる2つの解をもっても、その中にz=a があれば、障 りのx-a=0の解と同じになりx=αが重解になってしまう。 解が重なる場合を忘れるな ( 隣りの解に御用心) これで解決! (土) 500 00 78 解
