7x − y
-7x2 − y

Answer 1

Explanation:

Answer 2

Additive inverse is the number that when added to a number yields 0.

This is the negation of that number or expression.

The additive inverse of
`7x^2 + y` is
`-(7x^2 + y)`

Distribute the negative sign across all the terms in the parentheses. This is the same thing as multiplying each term by -1.


`-(7x^2 + y)`

`(-1 * 7x^2) + (-1 * y)`

`-7x^2 - y`
