To multiply the polynomials \((x^2y + 2)(x^2 - y)\), we can use the distributive property (also known as the FOIL method for binomials).
Here's how to do it step by step:
1. **Distribute \(x^2y\)**:
- \(x^2y \cdot x^2 = x^4y\)
- \(x^2y \cdot (-y) = -x^2y^2\)
2. **Distribute \(2\)**:
- \(2 \cdot x^2 = 2x^2\)
- \(2 \cdot (-y) = -2y\)
Now, combine all the terms:
\[
x^4y - x^2y^2 + 2x^2 - 2y
\]
So the simplified form of the polynomial multiplication \((x^2y + 2)(x^2 - y)\) is:
\[
x^4y - x^2y^2 + 2x^2 - 2y
\]
Thus, the correct response from the options provided is:
**x^4y − x^2y^2 + 2x^2 − 2y.**
