# How do you use synthetic division to divide (14x^2 - 34) by x+4?

Sep 30, 2015

$14 x - 56 + \frac{190}{x + 4}$

#### Explanation:

First, write down all the coefficients of $14 {x}^{2} - 34$. Make sure you include the coefficient $0$ for $x$.

For the number in the upper right box, set $x + 4$ to 0 and compute for $x$.
$x + 4 = 0$
$x = - 4$

The setup will look like this:
14 0 -34 |$\underline{- 4}$
