Answer:
-3n^3 - 2n^2 + 4.
Step-by-step explanation:
(3-7n^2+3n^3)-(6n^3-1-5n^2)
First distribute the negative over the second parentheses:
= 3 - 7n^2 + 3n^3 - 6n^3 + 1 + 5n^2
Now simplify like terms:
= -3n^3 - 2n^2 + 4 (answer).
Simplify
3 - 7n^2 + 3n^3 - (6n^3 - 1 - 5n^2)
Simplify brackets
3 - 7n^2 + 3n^3 - 6n^3 + 1 + 5n^2
Collect like terms
(3 + 10) + (-7n^2 + 5n^2) + (3n^3 - 6n^3)
Simplify
<u>4 - 2n^2 - 3n^3</u>
