数学[配方法解一元二次方程的]问题把1~100这100个数按下面规律排列:1,2,3,4,5,6,7,8,9,1011,12,13,14,15,16,17,18,19,20……91,92,93,94,95,96,97,98,99,100用一个长方形竖着任意框出1×3个位置上相邻的数（如1,11,2
数学[配方法解一元二次方程的]问题
把1~100这100个数按下面规律排列:
1,2,3,4,5,6,7,8,9,10
11,12,13,14,15,16,17,18,19,20
……
91,92,93,94,95,96,97,98,99,100
用一个长方形竖着任意框出1×3个位置上相邻的数（如1,11,21）.已知框出的这三个数中最大数与最小数的积比中间那个数的3倍多8,求这三个数.
数学[配方法解一元二次方程的]问题把1~100这100个数按下面规律排列:1,2,3,4,5,6,7,8,9,1011,12,13,14,15,16,17,18,19,20……91,92,93,94,95,96,97,98,99,100用一个长方形竖着任意框出1×3个位置上相邻的数（如1,11,2
设中间的数为X,则上面的数为X-10,下面的数为X+10,由题目可得
（X-10）（X+10）=3X+8
解之得：X=12 或者X= -9（舍） 因此这三个数分别是 2,12,22
