What is the difference of the two polynomials?

(7*y*2 + 6*xy*) – (–2*xy* + 3)

7*y*2 + 4*xy* – 3

7*y*2 + 8*xy* – 3

7*y*2 + 4*xy* + 3

7*y*2 + 8*xy* + 3

Let's solve the problem step by step.

### Step 1: Write down the given polynomials
1. First polynomial: \( 7y^2 + 6xy \)
2. Second polynomial: \( -2xy + 3 \)

### Step 2: Subtract the second polynomial from the first
\[
(7y^2 + 6xy) - (-2xy + 3)
\]

### Step 3: Distribute the negative sign across the second polynomial
\[
7y^2 + 6xy + 2xy - 3
\]

### Step 4: Combine like terms
- Combine the \( xy \) terms: \( 6xy + 2xy = 8xy \)
- The \( y^2 \) term stays as \( 7y^2 \).
- The constant \( -3 \) remains as is.

So, the simplified expression is:
\[
7y^2 + 8xy - 3
\]

### Conclusion
The correct answer is:
- **\( 7y^2 + 8xy - 3 \)**
