【分析】
既然不等式存在解集,说明一元二次方程x^2-a*x+a=0有解;
解之间横跨三个整数,说明Δ大于0;
三个整数必然是连续的,因为f(x)=x^2-a*x+a最多只与x存在两个交点,这是题设里的隐含条件。
【传统解法】
因为Δ>0,有a^2-4a>0,得到a∈(-∞,0)∪(4,+∞);
下面就这两段进行讨论。
(1)当a∈(-∞,0)即a<0时
若x取0,0^2-a*0+a=a<0,符合x^2-a*x+a<0,这说明3个连续整数中有一个是0;
若x取1,1^2-a*1+a=1>0,不符合x^2-a*x+a<0,这说明3个连续整数不会在0的右边,只可以向左走;
由于0是最右边的一个数,故三个连续整数是-2,-1,0;
由于f(x)=x^2-a*x+a开口向上,从图线上看,抛物线与x轴的交点一个在(0,1)之间,一个在(-3,-2)之间;
当交点在(0,1)之间时,必有f(1)>0,f(0)<0;
而f(1)=1-a+a=1>0,f(0)=0-0+a<0,这两个值是符合条件f(1)>0,f(0)<0的;
当交点在(-3,-2)之间,必有f(-3)>0,f(-2)<0;
而f(-3)=9+3a+a=9+4a>0,得到a>-9/4;
f(-2)=4+2a+a=4+3a<0,得到a<-4/3;
故a<0时,范围缩小为(-9/4,-4/3)
(2)当a∈(4,+∞)即a>4时
若x取0,f(0)=a>4>0,不符合x^2-a*x+a<0,说明0不是三整数之一;
若x取1,f(1)=1>0,不符合x^2-a*x+a<0,说明1也不是三整数之一;
若x取2,f(0)=4-a<0,符合x^2-a*x+a<0,说明2是三整数之一;
既然一直在向右走,三整数又是连续的,2是打头的数,故连续三整数是2,3,4;
由于f(x)=x^2-a*x+a开口向上,从图线上看,抛物线与x轴的交点一个在(1,2)之间,一个在(4,5)之间;
当交点在(1,2)之间,f(1)=1-a+a=1>0,f(2)=4-a<0,这两个值是符合条件的;
当交点在(4,5)之间,
f(4)=16-4a+a=16-3a<0,得到a>16/3;
f(5)=25-5a+a=25-4a>0,得到a<25/4;
故a>4时,范围缩小为(16/3,25/4)
最后,a的范围就是(-9/4,-4/3)∪(16/3,25/4)。
【得不到正确结论的传统解法】
方程x^2-a*x+a=0的右根是(a+(a^2-4*a)^0.5)/2,左根是(a-(a^2-4*a)^0.5)/2;
两根之间有三个连续整数,故2<(a^2-4*a)^0.5<3;
解此不等式得到a∈(-1.6,-0.828)∪(4.828,5.6)。
从中取值如5代入a,发现方程x^2-5x+5=0的两根间只有两个整数,说明此法是不正确的。
【程序思路】
程序解此题几乎可以直译。
首先用求根公式得到两个根;
其次设定a从-100变化到+100,步长为0.001,分别得到真实的两根值;
再取两根间的整数,如果是3个就符合条件了。
【Java代码】
import java.io.BufferedWriter; import java.io.FileOutputStream; import java.io.OutputStreamWriter; import java.util.ArrayList; import java.util.List; /** * 若不等式x^2-a*x+a<0的解集中恰有3个整数,求a的范围? * @author ufo * */ public class Test { public static void main(String[] args) throws Exception{ StringBuilder sb=new StringBuilder(); double a; for(a=-100;a<100;a+=0.001) { double min=(a-Math.sqrt(a*a-4*a))/2; double max=(a+Math.sqrt(a*a-4*a))/2; int realMin=(int)Math.ceil(min);// 大于min的最小整数 int realMax=(int)Math.floor(max);// 小于max最大整数 List ls=new ArrayList<Integer>(); for(int i=realMin;i<=realMax;i++){ ls.add(i); } if(ls.size()==3) { System.out.println("a="+a+" min="+min+" min="+max+" ls="+ls); sb.append("a="+a+" min="+min+" min="+max+" ls="+ls+"\n"); } } FileOutputStream writerStream = new FileOutputStream("240331.txt"); BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(writerStream, "UTF-8")); writer.write(sb.toString()); writer.close(); } }
从上看出,代码很简明,考虑到控制台输出有限,特地把结果输入到了文件中。

从以上结果来看,a∈(-2.25,-1.33)时,两根间的整数是[-2, -1, 0];
a∈(5.33,6.25时),两根间的整数是[2, 3, 4];
程序结果和传统解法是一致的。
【函数图像】
当a取6时,函数图像为
当取-2.5时,函数图像为
由图可见,两根间的整数确实符合题目和解答。

【结论】
一道数学题如果存在多种解法,那么最简洁的解法为最佳路径。
从这个意义上来说,程序解法已经比传统解法更优越。
