用二分法求函数f(x)=x^3-6x-1=0在x=2～5范围内的x=2附近的一个实根，其计算误差为|xl-x2|＜10^(-6)。完善下列程序。
Private Sub Command1 _Click ()
Dim V0 As Singke, v As Single, s As String
Dim x As Single, t As Single, x1 As Single, x2 As Single
x1 =0: x2=5
Do While()
x = (x1 +x2)/2
If Sgn(f1 (x)) = 1 Then
x2 = x
Else
x1 = x
End If
Loop
Print "x = "; x
