To find the product of the polynomials \((x^2y + 2)(x^2 - y)\), we can use the distributive property (also known as the FOIL method for binomials).
\[ (x^2y + 2)(x^2 - y) = x^2y \cdot x^2 + x^2y \cdot (-y) + 2 \cdot x^2 + 2 \cdot (-y) \]
Now, calculate each term:
- \(x^2y \cdot x^2 = x^{4}y\)
- \(x^2y \cdot (-y) = -x^2y^2\)
- \(2 \cdot x^2 = 2x^2\)
- \(2 \cdot (-y) = -2y\)
Now, combine all the terms:
\[ x^{4}y - x^{2}y^{2} + 2x^{2} - 2y \]
So the final result of the product of the polynomials \((x^2y + 2)(x^2 - y)\) is:
\[ x^{4}y - x^{2}y^{2} + 2x^{2} - 2y \]
Among the options provided, this corresponds to:
\(x^{4}y - x^{2}y^{2} + 2x^{2} - 2y\).
