Answer: B) 5h³- 5h² + 4h - 4
Explanation:
First, get rid of the parenthesis by distributing the negative sign to (3h³+5h²-3h - 7).
The expression is now 8h³ + h -11 - 3h³ - 5h² + 3h + 7
Now, combine like terms. Add terms with the same exponent. Let's start with the terms with the highest exponents.
8h³ + (- 3h³) = 5h³
- 5h²
h + 3h. = 4h
-11 + 7 = -4
Rewrite the new combined terms to get 5h³- 5h² + 4h - 4
