It seems like there might be a typo in your expression. If you meant to write \(3y^2 - 2y\), I can help with that.

If you're looking to find the difference between \(3y^2\) and \(-2y\), the expression is already given as the difference:

\[
3y^2 - (-2y) = 3y^2 + 2y
\]

Thus, the expression simplifies to:

\[
3y^2 + 2y
\]

This is the simplified form of the expression.

2. How would you factor the expression \(3y^2 + 2y\)?
3. What happens if you set \(y = 0\) in the expression \(3y^2 + 2y\)?
4. How does the expression \(3y^2 + 2y\) change if \(y = 1\)?
5. What is the derivative of the expression \(3y^2 + 2y\) with respect to \(y\)?

**Tip:** When dealing with polynomials, make sure to carefully manage the signs when performing operations like addition, subtraction, and factoring.
