To find the product of the polynomials \((x^2y + 2)(x^2 - y)\), we can use the distributive property (FOIL method for binomials).
1. Distribute \(x^2y\) to both terms in the second polynomial:
\[
x^2y \cdot x^2 = x^4y
\]
\[
x^2y \cdot (-y) = -x^2y^2
\]
2. Distribute \(2\) to both terms in the second polynomial:
\[
2 \cdot x^2 = 2x^2
\]
\[
2 \cdot (-y) = -2y
\]
3. Combine all the results:
\[
x^4y - x^2y^2 + 2x^2 - 2y
\]
Thus, the product of the polynomials \((x^2y + 2)(x^2 - y)\) is:
\[
x^4y - x^2y^2 + 2x^2 - 2y
\]
The correct response from the given options is:
**\(x^4y - x^2y^2 + 2x^2 - 2y\)**.
