Find the difference

(6a^(2)-7-3a^(3))-(7+a^(3)+2a^(2))

1 answer

Starting with the first set of parentheses:

6a^(2) - 7 - 3a^(3)

Distribute the negative sign to the terms inside the second set of parentheses:

6a^(2) - 7 - 3a^(3) - 7 - a^(3) - 2a^(2)

Combine like terms:

4a^(2) - 8 - 4a^(3)

Therefore, the difference between (6a^(2)-7-3a^(3)) and (7+a^(3)+2a^(2)) is:

4a^(2) - 8 - 4a^(3)
