Answer 16

18y^4 + 6y^3 +24y^2

ok first im going to factor 6y out right

then its going to me 6y ( 3y +y + 4+) ? im confused as to how the exponents work

Answer 17

you can factor out 6y^2...try it

Answer 18

6y^2 (3y^2+y+4y)

Answer 19

almost...
6y^2(3y^2 + y + 4)

you can check your work by multiplying the 6y^2 through the parenthesis...
6y^2 * 3y^2 = 18y^4
6y^2 * y = 6y^3
6y^2 * 4 = 24y^2

put them all together and you get :
18y^4 + 6y^3 + 24y^2 (your original problem)
