Answer

$2x^2 +x+5+\frac{6}{x-2}$.

Work Step by Step

The given expression is $(2x^3-3x^2+3x-4)\div(x-2)$ $\begin{matrix} & 2x^2 & +x &+5 ​& & \leftarrow &Quotient\\ &-- &-- &--&--& \\ x-2) &2x^3&-3x^2&+3x&-4 & \\ ​& 2x^3 & -4x^2 & & & \leftarrow &2x^2(x-2) \\ & -- & -- & & & \leftarrow &subtract \\ & 0 & x^2 & +3x & & \\ & & x^2 & -2x & & \leftarrow & x(x-2) \\ & & -- & -- & & \leftarrow & subtract \\ & & 0&5x &-4 & \\ ​& & & 5x& -10 & \leftarrow & 5(x-2) \\ & & & -- & -- & \leftarrow & subtract \\ & & & 0 & 6 & \leftarrow & Remainder ​\end{matrix}$ The answer is $\Rightarrow Quotient + \frac{Remainder}{Divisor}$ $\Rightarrow 2x^2 +x+5+\frac{6}{x-2}$.
