The equivalent expression for the given expression will be [tex]-4y^3+4y^2-6y+25[/tex].
The given expression is [tex](-4y^3 - 5y +16) + (4y^2 - y + 9)[/tex].
We have to find the final value of the expression.
Solve the given expression following the BODMAS rule as,
[tex](-4y^3 - 5y +16) + (4y^2 - y + 9)=-4y^3 - 5y +16+4y^2 - y + 9\\=-4y^3+4y^2-6y+25[/tex]
Therefore, the equivalent expression for the given expression will be [tex]-4y^3+4y^2-6y+25[/tex].
