Question

I don't understand this math. 2y^2-5+1+2y^2-6y^2-3-4y

Answer 1

Answer:

-2y^2 - 4y - 7

Step-by-step explanation:

If what you need to do is to combine like terms, then do this:

2y^2 - 5 + 1 + 2y^2 - 6y^2 - 3 - 4y =

= 2y^2 + 2y^2 - 6y^2 - 4y - 5 + 1 - 3

= -2y^2 - 4y - 7

Answer 2

Answer:

2y²-5+1+2y²-6y²-3-4y

Just combine like terms

2y²+2y²-6y²-4y-5+1-3

-5 + 1 -3= -7

2y²+2y²-6y²= -2y²

-2y²-4y-7

and we are done!
