Solve using quadratic formula?

Click For Summary
The discussion revolves around solving a system of equations involving θ1 and θ2, defined by θ1 + θ2 = γ and θ1 * θ2 = β. The user attempted to substitute θ2 with β/θ1, leading to a quadratic equation but ended up with four solutions, which contradicts their professor's assertion of only two valid solutions. Other participants suggest that the equations are symmetric, indicating that the user has essentially derived the same quadratic equation for both variables. This symmetry implies that the user has not made two distinct equations but rather one, which accounts for the perceived extra solutions. The conversation emphasizes the importance of recognizing the symmetry in the equations to avoid confusion in the solution process.

Homework Statement



Hey guys, recently, I struggled to solve this equation.
I need to find θ1 and θ2 by using this system of equations:

θ12
θ12

After letting θ2=β/θ1, I plugged this into the first equation. I got:

θ12-γθ1+β=0

At this point I get a very unsexy θ1 result by using quadratic solution.

Need you help!

P.S. This way, I get 4 solutions overall, but my professor is saying that there should only be 2 solutions.

What you've done so far is just fine. And I don't think the answer is going to pretty no matter how you do it.

How did you get 4 solutions? Could you show us? The point is that you must have made an error, and we cannot help until we know what you did.

If you look at your equations they are symmetric between θ1 and θ2. You could say there is no difference between θ1 and θ2. Or, do what you did to get a quadratic equation for θ1 but do it to get an equation for θ2 instead - you find you have got exactly the same equation for θ2 as you got for θ1.

You haven't really got two quadratic equations, you've got one.
