Answer:
[tex]-6y^2+5y+2[/tex]
Step-by-step explanation:
I'm assuming you want to simplify:
[tex]3y^2+5y-(4y^2+5)-8y^2-(-7-3y^2)[/tex]
Distribute to get rid of the ( ):
[tex]3y^2+5y-4y^2-5-8y^2+7+3y^2[/tex]
Put like terms together:
[tex]3y^2-4y^2-8y^2+3y^2+5y-5+7[/tex]
Combine the like terms:
[tex]-6y^2+5y+2[/tex]
