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).

Let's expand the expression:

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

So, the product of the polynomials \((x^2y+2)(x^2−y)\) is:
\[
x^4y - x^2y^2 + 2x^2 - 2y
\]

Among the provided options, the correct answer is:
**x^4y - x^2y^2 + 2x^2 - 2y**
