AnswEr :

\:\bullet\:\sf\ P(x) = x^3 - 3x^2 + x + 2

\:\bullet\:\sf\ q(x) = x - 2

\:\bullet\:\sf\ r(x) = -2x + 4

\:\bullet\:\sf\ g(x) =?

\normalsize\sf\bullet\:\ Here, \: we \: use \: Division \: algorithm \: \\ \normalsize\sf\ to \: find \: g(x)

 \rule{100}1

\normalsize\sf\:\:\:\:\:\qquad\:\underbrace{Division \: algorithm}

\normalsize\sf\qquad\:\underbrace{P(x) = g(x)  \times\ q(x) + r(x) }

\normalsize\sf\ [Dividend = Divisor \times\ quotient + Remainder]

\normalsize\dashrightarrow\sf\ P(x) = g(x) \times\ q(x) + r(x) \\ \\ \normalsize\dashrightarrow\sf\ x^3 - 3x^2 + x + 2 = g(x) \times\ (x - 2) + (- 2x + 4) \\ \\ \normalsize\dashrightarrow\sf\ x^3 - 3x^2 + x + 2 +2x - 4 = g(x) \times\ (x - 2) \\ \\ \normalsize\dashrightarrow\sf\ x^3 - 3x^2 + 3x - 2 = g(x) \times\ (x - 2) \\ \\ \normalsize\dashrightarrow\sf\frac{x^3 - 3x^2 + 3x -2}{(x -2)} = g(x)
