When the polynomial $f(x)$ is divided by $x - 3,$ the remainder is 15.  When $f(x)$ is divided by $(x - 1)^2,$ the remainder is $2x + 1.$  Find the remainder when $f(x)$ is divided by $(x - 3)(x - 1)^2.$
Question:
When the polynomial $f(x)$ is divided by $x - 3,$ the remainder is 15.  When $f(x)$ is divided by $(x - 1)^2,$ the remainder is $2x + 1.$  Find the remainder when $f(x)$ is divided by $(x - 3)(x - 1)^2.$
Answer:
Let's think step by step.
