#### Solution Preview

I am having difficulty with a few different problems.

1. (8x^7-4)(x^8-5)
After simplifying, we will get
= 8x^15 - 4x^8 - 40x^7 + 20

2. 5x^5-35x^4+40x^3
After taking 5x^3 common out, we will get
= 5x^3(x^2 - 7x + 8)

3. t^3-4t / t^2-64
t(t^2 - 4)/(t+8)(t-8)
= t(t-2)(t+2)/(t+8)(t-8)

If the question is ...
