Answer variants:

\frac{α + β}{α β}

9 α β - 3 (α + β) + 1

\frac{{(α^{2} + β^{2})}^{2} + 2 α β}{3 α β}

9 α β + 3 (α + β) - 1

\frac{{(α^{2} + β^{2})}^{2} - 2 α β}{3 α β}

\frac{α + β}{{(α β)}^{2}}

Write each of the following expressions in terms of \(\alpha + \beta\) and \(\alpha \beta\).

(i) \(\frac{\alpha}{3 \beta} + \frac{\beta}{3 \alpha} =\)

(ii) \(\frac{1}{\alpha^2 \beta} + \frac{1}{\beta^2 \alpha} =\)

(iii) \((3 \alpha - 1)(3 \beta - 1) =\)
