Question

What is the additive inverse of -7x2 + y? 7x2 + y 7x2 − y 7x − y -7x2 − y

Answer 1

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.

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