simplify the following expression:

Question

-2x^2 - 3y + x^2 + 8y + x^2 - z

Answer 1

To simplify the expression -2x^2 - 3y + x^2 + 8y + x^2 - z, we can combine like terms:

-2x^2 + x^2 + x^2 - 3y + 8y - z

Simplifying further:

(-2 + 1 + 1)x^2 + (-3 + 8)y - z

Reducing:

0x^2 + 5y - z

Finally, the simplified expression is:

5y - z
