Answer 3

I can help

Answer 4

We can only combine these terms:

5y^2 - 8y^2

Can you do that?

Answer 5

Just subtract the whole numbers and keep the variable with the exponent.

Answer 6

no I cant sorry

Answer 7

Subtract 5 - 8, what do you get?

Answer 8

iGreen... why do you always steal my questionsssss??..

Answer 9

Lol

Answer 10

You have to find like terms- this means analyzing the variables (\( x~,~y\)) etc and compare the power of their exponents.

Answer 11

3y^2

Answer 12

If they're the same, such as \(\color{red}{y^2}+3\color{red}{y^2}\) then you can add them.

Answer 13

Nice work, but 5 - 8 isn't 3

Answer 14

-3 sorry

Answer 15

Yes, so it's -3y^2

Answer 16

We are left with -3y^2, 4y, and 2y^3

Do you see any other like terms?

Answer 17

no i dont

Answer 18

Good :)

So we just arrange from highest exponent to lowest:

\(2y^3 - 3y^2 + 4y\)
