Question 1
The cubic equation $x^3 - 4x^2 + 5x - 2 = 0$ has roots $\alpha$, $\beta$, and $\gamma$. Find the value of $\alpha^2 + \beta^2 + \gamma^2$.
Correct Answer:
6
Question 2
Let $\alpha, \beta, \gamma, \delta$ be the roots of the quartic equation $x^4 + p x^2 + q x + r = 0$, where $r \ne 0$. Express $\frac{1}{\alpha} + \frac{1}{\beta} + \frac{1}{\gamma} + \frac{1}{\delta}$ in terms of the coefficients $p, q, r$.
Correct Answer:
$$-q/r$
Question 3
The roots of the equation $2x^3 - 3x^2 + 4x - 5 = 0$ are $\alpha, \beta, \gamma$. Find a cubic equation with integer coefficients whose roots are $2\alpha, 2\beta, 2\gamma$.
Correct Answer:
$$y^3 - 3y^2 + 8y - 20 = 0$
Question 4
The cubic polynomial $x^3 - 5x^2 + 7x - 3 = 0$ has roots $\alpha, \beta, \gamma$. Calculate the sum of cubes of the roots, $S_3 = \alpha^3 + \beta^3 + \gamma^3$.
Correct Answer:
29
Question 5
For the cubic equation $x^3 + ax + b = 0$ with roots $\alpha, \beta, \gamma$, express $S_4 = \alpha^4 + \beta^4 + \gamma^4$ in terms of $a$ and $b$.
Correct Answer:
$$2a^2$
