Find numbers given sum and product

What I have tried:

VB

Sub test()
 Dim sum, prod, outcounter, incounter
     prod = 1
For outcounter = 1 To Sheet1.Cells.Range("A1").Value
    For incounter = 1 To Sheet1.Cells.Range("A1").Value
        sum = outcounter + incounter
        prod = outcounter * incounter
        
        
        If sum = Sheet1.Cells.Range("A1").Value Then
            If prod = Sheet1.Cells.Range("A2").Value Then
                Sheet1.Cells.Range("B1").Value = outcounter
                Sheet1.Cells.Range("B2").Value = incounter
            GoTo found
            End If
        End If
        
    Next

Here is a fully optimized version of your macro. :-O

VB

Sub test()
End Sub

If only you had used your brain before programming, you should gave discovered that the problem is just about solving a quadratic equation.

I let you do the work of finding how to get the equation and the formula for solution.

Message to downvoter that don't give a solution:
Do the mathematical analyze and you will see that there is no need of a macro.
the solution is just 4 formulas (2 solutions and 2 variables) that fit in cells formulas.
And since this is Homework, just giving the full solution would earn me even more downvotes.
