Answer:
assuming that you want us to add them together here's the answer i got-
5y²−3y+3
Step-by-step explanation:
let us simplify step-by-step-
4y²−2y−5+y²(−y)+8
= 4y²+(−2y)+(−5)+y²+(−y)+8
combining like terms-
=4y²+−2y+−5+-y²+−y+8
=(4y²+y²)+(−2y+−y)+(−5+8)
=5y²+−3y+3
good luck :)
i hope this helps
brainliest would be highly appreciated
have a nice day!
