Answer:(-1, 5)
Step-by-step explanation:
Add X1 + X2 then divide by 2. Add Y1 + Y2 then divide by 2.

![x^5-8x^3-9x\\\\[Factor]x(x+3)(x-3)(x^2+1)\\\\[Set all the items equal to 0.]x = 0\\\\x+3=0\\x=-3\\\\x-3=0\\x=3\\\\x^2 +1=0\\x^2=-1\\x=i,-i](https://tex.z-dn.net/?f=x%5E5-8x%5E3-9x%5C%5C%5C%5C%5BFactor%5Dx%28x%2B3%29%28x-3%29%28x%5E2%2B1%29%5C%5C%5C%5C%5BSet%20all%20the%20items%20equal%20to%200.%5Dx%20%3D%200%5C%5C%5C%5Cx%2B3%3D0%5C%5Cx%3D-3%5C%5C%5C%5Cx-3%3D0%5C%5Cx%3D3%5C%5C%5C%5Cx%5E2%20%2B1%3D0%5C%5Cx%5E2%3D-1%5C%5Cx%3Di%2C-i)
The 5 roots are 0, -3, 3, i, and -i.
