化简后能求出系数就可以了

VB语言：
Private Function Change(Text As TextBox, label As label) As String
Dim Temp As Integer
If IsNumeric(Text.Text) Then
Temp = Text.Text
label.Caption = Chr(Temp + 64)
Else
MsgBox "请输入数字"
End If
End Function

Private Sub Command1_Click()
Change Text1, Label1
End Sub

(0.8a+0.3b)/(0.2a-0.7b)各项系数是？ {(a-b)/(a+b)}+{(b-c)/(b+c)}+{(c-a)/(c+a)}+{(a-b)(b-c)(c-a)/(a+b)(b+c)(c+a)} A*B=A+B/AB a^2+b^2/a+b 化简:(2a-b-c)/(a-b)(a-c)+(2b-c-a)/(b-c)(b-a)+(2c-a-b)/(c-a)(c-b) 化简：b/(a+b) + b/(a -b) +(a^2+b^2)/(a^2 -b^2) 求a/((a-b)(a-c))+b((b-c)(b-a))+c/((c-a)(c-b)) 求证:|a^2-b^2|/|a|≥|a|-|b| b/(a+b)=(a+c+-b)/(b+c-a)=(a+b+c)/(2a+b+2c)求a:b:c= 2a-b-c/(a-b)(a-c)+ab -c-a/(b-c)(b-a)+2c-a-b/(c-a)(c-b)
