gather like terms:
2y^2-4y^2 +4-(-1)
-2y^2+5
add the other terms not involved
6y^2-2y^2+2y+5
2y^2-4y^2 +4-(-1)
-2y^2+5
add the other terms not involved
6y^2-2y^2+2y+5

I do not understand. I got the wrong answer. Like 4y^2+5y+5

(6y^2+2y^2+2y+4)-(4y^2-1)
= (8y^2+2y+4)-(4y^2-1)
= 8y^2+2y+4-4y^2+1
= 4y^2+2y+5
No idea where the 5y came from, unless there's a typo.
