1.3.1 Operations on polynomials

Question 5

A company's weekly profit $P$ , in thousands of pounds, is modeled by the polynomial $P(n) = 5n^3 + kn^2 + 8n - 30$ , where $n\,$ is the number of units sold (in hundreds) and $k\,$ is a constant. A financial analysis reveals that when $P (n)$ is divided by $(n - 2)$ , the remainder is 2. Find the value of $k$ .
