$(-4,-\frac{1}{2})\\$

Step-by-step explanation:

The midpoint between two points can be calculated by $(\frac{x_1 +x_2}{2}, \frac{y_1 +y_2}{2})\\$ where x_n and y_n is the -coordinates of point .

In your case we have two endpoints: A(-5,-4) and B(-3,3) . So the midpoint can be calculated as:

$(\frac{x_A +x_B}{2}, \frac{y_A +y_B}{2}) \\ (\frac{-5 +(-3)}{2}, \frac{-4 +3}{2}) \\ (\frac{-5 -3}{2},\frac{-4 +3}{2}) \\ (\frac{-8}{2},\frac{-1}{2}) \\ (-4,-\frac{1}{2})$

The midpoint of $\overline{AB}$ is $(-4,-\frac{1}{2})\\$

Mathematics

Using the synthetic division algorithm (see attached for a completed table), we have

$\dfrac{x^4-3x^3-14x^2-x+19}{x+1} = \underbrace{x^3 - 4x^2 - 10x + 9}_{q(x)} + \dfrac{\overbrace{10}^{r(x)}}{\underbrace{x+1}_{b(x)}}$

Use synthetic division to find the result help please
