Answer 1

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).

We can expand it as follows:

1. Multiply \(x^2y\) by \(x^2\): \[ x^2y \cdot x^2 = x^4y \]

2. Multiply \(x^2y\) by \(-y\): \[ x^2y \cdot (-y) = -x^2y^2 \]

3. Multiply \(2\) by \(x^2\): \[ 2 \cdot x^2 = 2x^2 \]

4. Multiply \(2\) by \(-y\): \[ 2 \cdot (-y) = -2y \]

Now, we combine all of these results: \[ x^4y - x^2y^2 + 2x^2 - 2y \]

Thus, the product of the polynomials \((x^2y + 2)(x^2 - y)\) is: \[ \boxed{x^4y - x^2y^2 + 2x^2 - 2y} \]

Therefore, the correct response is:

• \(x^4y - x^2y^2 + 2x^2 - 2y\)
