编写程序,求一元二次方程ax^2 bx c=0解

PrivateSubCommand1_Click()DimaAsSingle,bAsSingle,cAsSingleDimdAsSingle,x1AsSingle,x2AsSinglea=InputB

什么程序?c语言的?说下想法吧先求△=b²-4ac之后分类判断（1）△0,x=(-b±根号（b²-4ac）)/(2a)再问：能不能写成IF……ELSE……end……的形式再答：de

请参考

第二题：#includevoidmain(){inti,g,s,b;for(i=100;i

C++的代码：#include#includevoidmain(void){doublea,b,c,d;charch('y');do{coutb>>c;if(-0.0001

#include#include

两处错误,第一个,没有赋值过程,应该改为：a=InputBox("a=")b=InputBox("b=")c=InputBox("c=")第二个：x1=(-b-d)/(2*a)应该是x2=(-b-d)
