写真に問題と解答が載っています。 なぜk=3、α=12と出た時点でそれぞれをア→3 イ→12と答えにしてはいけないのかを教えて下さい！

練習 2つの2次方程式x°+6x+12k-24=0, x+(k+3)x+12=0がただ1つの実数を共通解として 99 もつとき, 実数の定数 kの値はアコであり, そのときの共通解はイ である。 [類中京大) 共通解をx=Q とおいて, 方程式にそれぞれ代入すると α?+6α+12kー24=0 a+(k+3)α+12=0 (k-3)α-12k+36=0 (k-3)(α-12)=0 の 2 の-0 から そaの項を消去。 ゆえに Sore よって k=3, α=12 [1] k=3のとき 2つの2次方程式はともにx+6x+12=0 となり,この方程 D 式の判別式をDとすると =3°-1·12=-3 4 D<0であるから, この方程式は実数解をもたない。 ゆえに, 2つの方程式は共通の実数解をもたない。 [2] α=12 のとき のから 12+6-12+12k-24=0 そx°+6x+12 =(x+3)°+3>0 から示してもよい。 よって k=-16 そ2に代入してもよい。 このとき, 2つの2次方程式は x°+6x-216=0, x°-13x+12=0 すなわち(x-12)(x+18)=0, (x-1)(x-12)=0 解はそれぞれ x=12, -18; ゆえに, 2つの方程式はただ1つの共通の実数解 x=12 をも -216=6°=2°-3° x=1, 12 つ。 SS 以上から k=アー16, 共通解はイ12 日

Time was limited. Chiune wrote visas day Chiune wrote visas da, little. His arm became 4 and night. He ate very little. His arm On his last day, he went to the station to leave for Berlin. A lot of Jewish people were waiting for him there. So Chiune kept writing Visas while on the train. When the train started to leave, he handed out the last visa from the train window and cried out, “T'm really sorry. I cannot write any more visas. I truly hope Sore, everyone will be safe." Someone shouted to 10 Chiune, “Mr. Sugihara, we will not forget you. Someday we will meet you again."
