Answer:
![x + 9 = - 5x + 9 = 45 \\ x + 5x = 9 - 9 = 45 \\ 6x = 0 = 45 \\ 6x = 45 \\ x = 7.5](https://tex.z-dn.net/?f=x%20%2B%209%20%3D%20%20-%205x%20%2B%209%20%3D%2045%20%5C%5C%20x%20%2B%205x%20%3D%209%20-%209%20%3D%2045%20%5C%5C%206x%20%3D%200%20%3D%2045%20%5C%5C%206x%20%3D%2045%20%5C%5C%20x%20%3D%207.5)
this the best I can do
Step-by-step explanation:
Good luck
Let
![f(x)=-2x^3+14x^2+24x+20](https://tex.z-dn.net/?f=f%28x%29%3D-2x%5E3%2B14x%5E2%2B24x%2B20)
. You have
![f(5)=240](https://tex.z-dn.net/?f=f%285%29%3D240)
, which means - by the polynomial remainder theorem - that the remainder upon dividing
![f(x)](https://tex.z-dn.net/?f=f%28x%29)
by
![x-5](https://tex.z-dn.net/?f=x-5)
is 240, and so
![x-5](https://tex.z-dn.net/?f=x-5)
is not a factor of
![f(x)](https://tex.z-dn.net/?f=f%28x%29)
.
