［3］の解説お願いします🙇

xの2次方程式x2 +mx+1 = 0, x2+mx+m=0 がともに実 数解をもたないような定数mの値の範囲は [3]である。 D₁ = m² - 4.1.1 = (m + 2)(m − 2) <0-2 <m << 2 0<m <4 D₂ = m² -4.1 m = m(m-4) < 0 ⇒ 0<m<4

この2次不等式の解説お願いします🙇

[x²2-2x-2≧0

途中式の枠で囲っている所の計算が分かりません💦 解説お願いします🥺

7 次の条件を満たす放物線をグラフにもつ2次関数を求めよ。 y=x2のグラフを平行移動したもので, 点 (1,1)を通り, 頂点が線 y=-x-4上にある。 10 頂点を支(t-t-4) とおく。 y=xのグラフを平行移動したものなので 求める2次関数はy=(x-t)^-+-4と表される。 5 (1,1)を通るので11=11-+-+-4 t-3t-4=0 (t-4)(t+1)=0 t=4-1 よって.y=(x-4)=8,y=(x+1-3

写真の16番について添削お願いします 人目を気にする→他人からの評判を気にする、社会に出た時→仕事を得た時(働き始めた時)、世の中の人→たくさんの大人　と訳したのですがどうでしょうか

君はまだ若くて健康なのだから、少しぐらいの間違いは気にし なくてもよい。 思うことをためらわずに実行に移したまえ。 世の中の人は、人目を気にしたり、外見だけで人を判断するこ とが多いなと、社会に出たとき感じました。 ( 15 : 第一薬科大学/⑩ : 京都府立大学)
