Answer variants:
1. Write the expression \(\frac{\alpha + 3}{\beta} + \frac{\beta + 3}{\alpha}\) in terms of \(\alpha + \beta\) and \(\alpha \beta\).
Answer:
The solution is .
2. The roots of the equation \(2x^2 - 7x + 5 = 0\) are \(\alpha\) and \(\beta\). Without solving for the roots, find \(\frac{1}{\alpha} + \frac{1}{\beta}\).
Answer:
