Question

(5h​3​​−8h)+(−2h​3​​−h​2​​−2h)

Answer 1

(5h^3-8h)+(-2h^3-h^2-2h)

First, you would distribute into parentheses but there is nothing

5h^3-8h-2h^3-h^2-2h

Now, separate all into common terms

(5h^3-2h^3)(h^2)(-8h-2h)

Now simplify

3h^3h^2-10h

Answer 2

(5h^​3 ​​− 8h) + (−2h​^3 ​− h^​2 ​​− 2h)
= 5h^3 - 8h - 2h^3 - h^2 - 2h
= 3h^3 - h^2 - 10h
