-$$\left( 8 r ^ { 3 } - 60 r ^ { 2 } - 27 r - 40 \right) \div ( r - 8 )$$
A) $r ^ { 2 } + 5 r + 4$
B) $8 r ^ { 2 } + 4 r + \frac { 5 } { r - 8 }$
C) $8 r ^ { 2 } + 4 r + 5$
D) $8 r ^ { 2 } - 4 r - 5$

To use synthetic division, we set up the divisor in the following form: $\begin{array}{c|cccc} & 8 & -60 & -27 & -40 \ \hline 8 & & 64 & 4 & 5\end{array}$

The remainder is 5, and the quotient is $8r^2+4r+5$. Thus, the answer is C.

Use Synthetic Division to Divide (8r3−60r2−27r−40)÷(r−8)\left( 8 r ^ { 3 } - 60 r ^ { 2 } - 27 r - 40 \right) \div ( r - 8 )(8r3−60r2−27r−40)÷(r−8)

Use Synthetic Division to Divide $\left( 8 r ^ { 3 } - 60 r ^ { 2 } - 27 r - 40 \right) \div ( r - 8 )$
