x4y+x2−2y
x superscript 4 baseline y plus x squared minus 2 y

x3y−x2y2+2x2−2y
x cubed y minus x squared y squared plus 2 x squared minus 2 y

x4y−x2y2+2x2−2y

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 break it down step-by-step:

1. **Distribute each term in the first polynomial by each term in the second polynomial**:
- \(x^2y \cdot x^2\) gives \(x^4y\)
- \(x^2y \cdot (-y)\) gives \(-x^2y^2\)
- \(2 \cdot x^2\) gives \(2x^2\)
- \(2 \cdot (-y)\) gives \(-2y\)

2. **Combine all the terms**:
\[
x^4y - x^2y^2 + 2x^2 - 2y
\]

Thus, the final product is \(x^4y - x^2y^2 + 2x^2 - 2y\).

Now let's match this with the provided options:

- \(x^4y - x^2y^2 + 2x^2 - 2y\)

This matches the fourth response option:
**x4y−x2y2+2x2−2y**.

So, the correct answer is:

**x4y−x2y2+2x2−2y**.
