What are Vieta's Formulas in Polynomial Functions?

I say the answer is A.

Did you check it? Did the roots come out? (They don't.)

There are three ways to do this one.
1) Cheat and find the roots of all your possible answers.

2) Use the Vieta formulas.

3) Write out [math](x - 1) \left ( x - \dfrac{1}{ \alpha } \right ) = 0[/math] and expand.

No. I did not check it. What is the Vieta formulas?

Beer soaked ramblings follow.

No. I did not check it. What is the Vieta formulas?

Translation: I don't know man. That sounds like a lot of work!

Vieta's formulas are equations that connect some expressions of the roots of a polynomial equation to its coefficients. (See e.g. wikipedia)

I'll need to look that up.
