[tex]\boxed{\bold{2y^2-4y-24}}[/tex]
Step By Step Explanation:
Expand [tex]\bold{3\left(2y-8\right): \ 6y-24}[/tex]
[tex]\bold{6y-24-2y\left(5-y\right)}[/tex]
Expand [tex]\bold{-2y\left(5-y\right): \ -10y+2y^2}[/tex]
[tex]\bold{6y-24-10y+2y^2}[/tex]
Simplify [tex]\bold{6y-24-10y+2y^2}[/tex]
[tex]\bold{2y^2-4y-24}[/tex]
