利用上述结论解决:若代数式4x-3/x-1的值为整数,求满足条件的整数x的值
探索:(1)如果3x-2/x+1=3+m/x+1则m=-5(2)如果5x-3/x+2=5+m/x+2则m=-13总结:如果ax+b/x+c=a+m/x+c(其中a,b,c...
探索:(1)如果3x-2/x+1=3+m/x+1则m=-5
(2) 如果5x-3/x+2=5+m/x+2则m=-13
总结:如果ax+b/x+c=a+m/x+c(其中a,b,c为常数),则m=b-ac
给我解题思路,要讲清楚! 展开

4x-3/x-1=4+m/x-1
m=1
4x-3/x-1=4+1/x-1
x=2
m=1
4x-3/x-1=4+1/x-1
x=2
