写真の(1)の問題で､自分の解答は合っているか教えてほしいです🙇🏻‍♀️ 模範解答は場合分けをしてから普通に2次方程式を解いていますが自分は場合分けをして判別式が0以上になっているかを考えて解きました。

【5】 pを実数の定数とする. xの2次方程式 x2-(2p+|p|-|p+1|+1)x + 1/2(2p+30|p+1|-1)=0 について次の各設問に答えよ. (1)この2次方程式は実数解をもつことを示せ. (2)この2次方程式が異なる2つの実数解α, βをもち, かつ a2 + 2 ≦1となるような定数 p の値の範囲を求めよ、 x-(2p+|p|-|p +1 +1)x +1/2(2p+3|p|-|p+1|-1)=0……① (1) p < 1 のとき, 方程式 ①を解くと x-{2p-p-(-p-1)+1}x +1/2{2p-3p-(-p-1)-1} = 0 x-2(p +1)x=0 x{x-2(p+1)}=0 :.x=0,2(p+ 1) であるから, 方程式 ① は実数解をもつ. -1≦p < 0 のとき, 方程式 ① を解くと x²-{2p-p-p +1)+1}x +1/2{2p-3p-(p+1)-1} = 0 p-1のとき 2 + B2 ≦1 02 + {2(p + 1)} ≦1 {2p+1)}2-1≦0 {2(p +1) +1}{2(p+1)-1}≦0 (2p+3)(2p+1) ≦ 0 . - ≤ p < -1 である. -1 <p < 0 のとき (√P+1)²+(-√P+1) SI ps-12 であり,-1<p < 0 より ≦1 x=p+1(≧0) である. ..x = √ p+1 であるから, 方程式 ① は実数解をもつ. p≧0 のとき, 方程式を解くと x-{2p+p-p+1) +1}x +1/2{2p+3p-(p+1)-1} = 0 x2-2px+2p-1=0 0<p<1,1<pのとき (p+lp-1)2 + (p-lp-1)2≦1 4p2-4p+1≦0 (2p-1)²≤0 :. p= 2 であり,これは0p<11<p を満たす. 以上より, 求める定数 pの値の範囲は :.x=p±lp-1| -sp<-1, -1<ps - 1/1, p = 1/ であるから, 方程式 ① は実数解をもつ. 以上より、題意は示された. ☐ である. (2) 異なる2つの実数解をもつような, 定数の値の範囲 は (1) より である. p<-1, -1 < p<1,1<p

However, when he was a child, his family moved to Portland, Oregon, where he attended 問1の正解の根拠 ~へ引っ越した 〜に通った school. When he was young, a game he used to play by himself was to look at, よくしたものだ 一人で for example, a bird, and try to imagine what it would sound like if it could talk. Then, he would try to make the voice that he had imagined. 問1の正解の根拠 ~を集めた 問1の正解の根拠 3 In 1927, Blanc began working for a daily radio program. There, because the sponsors could not afford to hire more actors, Blanc used his own voice for many of the show's characters. After that, he moved to Los Angeles, California, where he joined Leon Schlesinger Productions, an animation studio that had assembled some of the greatest voice actors of the time. This company did the work for Warner Brothers, which developed the cartoons that made Blanc rotair lo subiq soloqu na diw envoys abiyong liw 4 Without a doubt, Blanc's most famous voice is that of Bugs Bunny, the star of the Warner Brothers animated line-up since 1940.
