solve ax+b=0 急!! plz help 20點!
發問:
solve the linear equation ax+b=0 don't tell me that x= -b/a
最佳解答:
1、If a=0 , then b=0, x can be any real number. eg. (0)x+b=0 0+b=0 b=0 2、If a≠0, then x=-b/a, and b can be any real number. eg. 2x+b=0 2x=-b x=-b/2 if there is any problem please comment~
should we consider the case when a=0 and b<>0 as well ?|||||"don't tell me that x= -b/a" Then what should I tell you?????
