How do you work out this problem?

3x3 + 2x2 + 3x+2
I showed three different people my work an they said I did it wrong I am so confuse.

hard to say what's wrong, since you don't say what you're trying to do.

factor it? Rearrange things a bit:

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

If the cost of a cell phone has decreased 400% during the past 10 years, does that correspond to a cost decrease of four times? Explain your answer as though you were talking to someone who has never taken algebra.

(3x^2y^3)^3

To work out the problem, you need to simplify the given expression. Let's break it down step by step.

The expression is: 3x³ + 2x² + 3x + 2

Step 1: Group the terms with the same power of x.
(3x³ + 2x²) + (3x + 2)

Step 2: Within each group, combine like terms.
For the first group, 3x³ + 2x², there are no like terms to combine.

For the second group, 3x + 2, there are no like terms to combine.

Step 3: Put the simplified groups back together.
(3x³ + 2x²) + (3x + 2)

Now, let's take a look at your work to identify the possible mistakes:

Mistake 1: Incorrect grouping
Make sure you group terms with the same power of x together. It seems like you might have missed this step.

Mistake 2: Incorrect simplification
If you combined terms within each group, you should have ended up with two separate simplified groups. It's possible you didn't simplify each group correctly.

To further assist you, could you provide the specific steps you took in your work? That way, I can pinpoint the exact mistakes and help clarify any confusion you may have.
