この問題の⑵なんですが、 三枚目のm>4あたりの場合分けで、 場合分けⅠは②の点が3より上にあることが 条件なのに、なぜ場合分けⅡでは②上の点が③より下、または③の上にあるのが条件なんですか? (Ⅰは5,24という上の点を基準にしているのに Ⅱで下の3,8を基準にしている理... Read More

102 2次方程式・2次不等式の整数解 整数mに対し, f(x)=x-mx+"-1 とおく。 (1) 方程式f(z)=0 が,整数の解を少なくとも1つもつようなの値を求め よ。 (2) 不等式 f(x) ≧0 を満たす整数xが,ちょうど4個あるようなmの値を求 めよ。 (秋田大) f(x) の式にはmの1次の項しか含まれていないことに着目する と, f(x)=0, f(x) ≧0 は “パラメタの分離” によって, 放物線 精講 y=-1と直線y=m(x-121) の関係に帰着されます。 解答 また,整数問題とみなすと, (1)では解と係数の関係を利用して2つの整数解 の満たすべき関係式が導かれます。 (2)では, 不等式 f(x) ≧0 を満たす整数が ちょうど4個であるとき, 不等式の解の区間幅からmを絞りこむ方法もありま す。 (1) 2次方程式 f(x)=0, つまり x2-mx+ -1=0 m x2-1=mx ²-1= m(x-1) ......1 の実数解は放物線y=x2-1 ・②と直線 y=m(x-1) •••••• ③ の共有点のx座標に等し 第1章 ① において, (2解の和)=mが整数であるから, 解の1つが整数のとき、 他の解も整数である。した がって“②③ 2つの共有点をもち,それらの 座標が整数である”..… (*) ようなmの値を求め るとよい。
