Question

Help pass due! i need all help i can get!

Simplify (8h³+h-11) - (3h³+5h²-3h - 7)
a) 11h³ + 5h² - 2h - 18
b) 5h³- 5h² + 4h - 4
c) 11h³ - 5h² +4h - 4
d) 5h³ + 5h² - 2h + 4

Answer 1

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

Answer 2

b) 5h³-5h²+4h-4
