Answer 2

To simplify the expression, let's start by distributing the negative sign to the terms within the parentheses:

(2x^2 + y^2 + z^2) - (3x^2 - 2y^2 + 2z^2)

Now, distribute the negative sign to each term inside the parentheses:

2x^2 + y^2 + z^2 - 3x^2 + 2y^2 - 2z^2

Next, combine like terms. Group the x^2 terms, the y^2 terms, and the z^2 terms:

(2x^2 - 3x^2) + (y^2 + 2y^2) + (z^2 - 2z^2)

Simplifying each group of like terms:

-x^2 + 3y^2 - z^2

Therefore, the simplified expression is -x^2 + 3y^2 - z^2.
