ok, i need help w/ this problem.

(4x^3 + x^2 + 3) + (x^3 + 2x^2 +1)
can u please explain how to do this please? i'm very lost. Thanx!

whoops, sorry i didn't mean to post twice!

gather like terms..

(4x^3 + x^3)+(x^2 + 2x^2) +(3+1)....

No problem, Ally! I can help you with that.

To solve this problem, you need to combine like terms within each term and then combine the terms together. Like terms have the same variable and exponent.

Let's break it down step by step:

First, we group the terms with the same variables:

(4x^3 + x^2 + 3) + (x^3 + 2x^2 + 1)

Now, let's simplify each pair of like terms within the parentheses:

4x^3 + x^3 = (4 + 1)x^3 = 5x^3

x^2 + 2x^2 = (1 + 2)x^2 = 3x^2

3 + 1 = 4

Now, we can combine these simplified terms. Rewrite the expression with the simplified terms:

5x^3 + 3x^2 + 4

And that's the final answer after combining like terms: 5x^3 + 3x^2 + 4.

I hope this explanation helps! Let me know if you have any more questions.
