Respuesta :
This polynomial would simplified as: -2y^7-2xy^4-x^8y^2-6xy (I'm assuming you meant to square the answers)
If you didn't the answer would be: -30xy-14y
But I'm pretty sure you meant to put the first one!
Answer:
[tex](-2y^{7}-2xy^{4}-x^{8} y^{2}-6xy)[/tex]
Step-by-step explanation:
The given expression is [tex]xy^{4}+5y^{7}-(6xy-7y^{7})-x^{8}y^{2}(-3xy^{4})[/tex]
We have to simplify the given expression.
[tex]xy^{4}+5y^{7}-6xy-7y^{7}-x^{8}y^{2}-3xy^{4}[/tex]
[tex](xy^{4} -3xy^{4})+(5y^{7}-7y^{7})-6xy-x^{8}y^{2}[/tex]
[tex]-2xy^{4}-2y^{7}-6xy-x^{8} y^{2}[/tex]
[tex]-2xy^{4}-2y^{7}-6xy-x^{8}y^{2}[/tex]
Therefore, simplified form of the expression will be
[tex](-2y^{7}-2xy^{4}-x^{8} y^{2}-6xy)[/tex]
