If (\alpha,\beta) are roots of (x^2-11x+30=0), what is the correct value of (\frac{\alpha+1}{\alpha-1}+\frac{\beta+1}{\beta-1})?

Answer and explanation

Correct answer: (\frac{19}{5})

The roots are (5) and (6). Direct substitution gives (\frac{6}{4}+\frac{7}{5}=\frac{29}{10}), so none of the given options is correct.
