Formula
Calculate the value
Use the synthetic division to find the quotient and the remainder
$\left( -4x ^{ 3 } +6x ^{ 2 } +5 \right) \div \left( 2x+1 \right)$
$- \dfrac { 4 x ^ { 3 } - 6 x ^ { 2 } - 5 } { 2 x + 1 }$
Arrange the rational expression
$\left ( \color{#FF6800}{ - } \color{#FF6800}{ 4 } \color{#FF6800}{ x } ^ { \color{#FF6800}{ 3 } } \color{#FF6800}{ + } \color{#FF6800}{ 6 } \color{#FF6800}{ x } ^ { \color{#FF6800}{ 2 } } \color{#FF6800}{ + } \color{#FF6800}{ 5 } \right ) \color{#FF6800}{ \div } \left ( \color{#FF6800}{ 2 } \color{#FF6800}{ x } \color{#FF6800}{ + } \color{#FF6800}{ 1 } \right )$
 Calculate the multiplication expression 
$\color{#FF6800}{ - } \color{#FF6800}{ \dfrac { 4 x ^ { 3 } - 6 x ^ { 2 } - 5 } { 2 x + 1 } }$
 Quotient $: - 2 x ^ { 2 } + 4 x - 2 \\$ Remainder $: 7$
Use the synthetic division to find the quotient and the remainder
$\left ( \color{#FF6800}{ - } \color{#FF6800}{ 4 } \color{#FF6800}{ x } ^ { \color{#FF6800}{ 3 } } \color{#FF6800}{ + } \color{#FF6800}{ 6 } \color{#FF6800}{ x } ^ { \color{#FF6800}{ 2 } } \color{#FF6800}{ + } \color{#FF6800}{ 5 } \right ) \color{#FF6800}{ \div } \left ( \color{#FF6800}{ 2 } \color{#FF6800}{ x } \color{#FF6800}{ + } \color{#FF6800}{ 1 } \right )$
 Divide $- 4 x ^ { 3 } + 6 x ^ { 2 } + 5$ by $2 x + 1$ using the synthetic division 
 Quotient $: - 2 x ^ { 2 } + 4 x - 2 \\$ Remainder $: 7$
