How do you find the sum or difference of #(3n^3-5n+n^2)-(-8n^2+3n^3)#?

Answer 1

See the entire solution process below:

First, remove all of the terms from parenthesis. Be careful to handle the signs of each individual term correctly:

#3n^3 - 5n + n^2 + 8n^2 - 3n^3#

Next, group like terms:

#3n^3 - 3n^3 + n^2 + 8n^2 - 5n#

Now, combine like terms:

#3n^3 - 3n^3 + 1n^2 + 8n^2 - 5n#
#(3 - 3)n^3 + (1 + 8)n^2 - 5n#
#0n^3 + 9n^2 - 5n#
#9n^2 - 5n#

Answer 2

#n(9n-5)#

#(3n^3-5n+n^2)-(8n^2+3n^3)#
#:.=3n^3-5n+n^2+8n^2-3n^3#
#:.=9n^2-5n#
#:.=n(9n-5)#

Answer 3

To find the sum or difference of ((3n^3 - 5n + n^2) - (-8n^2 + 3n^3)), first remove the parentheses and then combine like terms:

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

Combine like terms:

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

(0n^3 + 9n^2 - 5n)

So, the sum or difference is (9n^2 - 5n).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
