Question

What is the additive inverse of the polynomial? -7y^2+x^2y-3xy-7x^

Answer 1

The additive inverse of the polynomial $- 7{y^2} + {x^2}y - 3xy - 7{x^2}$ is $\boxed{7{y^2} - {x^2}y + 3xy + 7{x^2}{\text{ or }} - \left( { - 7{y^2} + {x^2}y - 3xy - 7{x^2}} \right)}.$

Further explanation:

Given:

The polynomial is $- 7{x^2} + {x^2}y - 3xy - 7{x^2}.$

Explanation:

The given polynomial is $- 7{y^2} + {x^2}y - 3xy - 7{x^2}.$

The additive inverse can be defined as when we add a number to some number and get result as zero.

The value of additive inverse is same as of the number but the sign of the additive inverse is opposite.

The additive inverse of the polynomial can be expressed as follows,

$\begin{aligned}A&= - 7{y^2} + {x^2}y - 3xy - 7{x^2} + \left( {7{y^2} - {x^2} + 3xy + 7{x^2}} \right)\\&= - 7{y^2} + 7{y^2} + {x^2}y - {x^2}y - 3xy + 3xy - 7{x^2} + 7{x^2}\\&= 0\\\end{aligned}$

The additive inverse of the polynomial $- 7{y^2} + {x^2}y - 3xy - 7{x^2}$ is $\boxed{7{y^2} - {x^2}y + 3xy + 7{x^2}{\text{ or }} - \left( { - 7{y^2} + {x^2}y - 3xy - 7{x^2}} \right)}.$

Answer 2

That is the thing that makes it negative
basically, the addative invsers of a is -a
addative inverse of -7y^2+x^2y-3xy-7x^2 is -(-7y^2+x^2y-3xy-7x^2) or 7y^2-x^2y+3xy+7x^2
