Solve the expressions — task. Maths TNSB Mentoring, Class 10.

Determine:

\frac{a^{2} - 16}{a^{3} - 8} \times \frac{2 a^{2} - 3 a - 2}{2 a^{2} + 9 a + 4} \div \frac{3 a^{2} - 11 a - 4}{a^{2} + 2 a + 4}

\(=\)

Answer variants:

\(\frac{a+1}{a-1}\)

\(\frac{3a+5}{3a-5}\)

\(\frac{1}{3a+1}\)

\(\frac{5a-6}{5+6a}\)
