It is given that

$P(x) = 2x^3 + 9x^2 + 13x + 6$

Use the factor theorem to show that $(2 x + 3)$ is a factor of $P (x)$ .

Express $P (x)$ as a product of three linear factors.

Given that $n\,$ is a positive integer, use your answer to part (b) to explain why $2n^3 + 9n^2 + 13n + 6$ is never prime.
