The coordinates of C must be (8,10).

If you plug in the values given in the midpoint formula
$8= \frac{8+(8)}{2}$
and $15= \frac{20+(10)}{2}$

it matches perfectly with the provided midpoint

The mid point is 5 away from d so it should be five away from c. 8,5

D₁ vide using x² - 2x² 2× +3× -5 by ×-3 using synthetic division. <br>

Vaselesa [24]

Answer:

Step-by-step explanation:

I think you are trying to use synthetic division for

$x^{4} -2x^{3} -2x^{2} +3x-5$ divided by x-3

First

x -3 = 0 , make it equal to 0 and add 3 to both sides

x = 3

Then we write all the coefficients and continue with

a pattern of multiply by 3 and add to the next coefficient.
