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).

  1. First, distribute \(x^2y\): \[ x^2y \cdot x^2 = x^4y \] \[ x^2y \cdot (-y) = -x^2y^2 \]

  2. Next, distribute \(2\): \[ 2 \cdot x^2 = 2x^2 \] \[ 2 \cdot (-y) = -2y \]

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

Thus, the product of the polynomials is: \[ x^4y - x^2y^2 + 2x^2 - 2y \]

The correct response from your options is: x^4y - x^2y^2 + 2x^2 - 2y (or "x4y−x2y2+2x2−2y").
