Polynomial Function

In summary, the conversation discusses three possible ways to find the roots of a polynomial equation, including cheating, using Vieta's formulas, and expanding an equation. The Vieta formulas are equations that relate the roots to the coefficients of the equation.

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 \(\displaystyle (x - 1) \left ( x - \dfrac{1}{ \alpha } \right ) = 0\) and expand.

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.
