I don't even know where to begin with this problem.
multiply
(2y+5w+6)(5y+5w4)

Use the same pattern as you use in FOIL
(2y+5w+6)(5y+5w4)
= 2y(5y) + 2y(5w) + 2y(4) + 5w(5y) + ...
= 10y^2 + 10wy  8y ...
combine all like terms 
ok I finished the problem. Is this right?
2y(5y)+ 2y(5w) + 2y(4) + 5w(5y) + 5w(5w)+ 5w(4) + 6(5y) + 6(5w) + 6(4)
then I multiplied:
10y^2 + 10wy  8y + 25wy + 25w^2  20w + 30y + 30w  24
then I combined like terms:
10y^2 + 15wy + 25w^2 + 22y + 10w  24
final answer:
10y^2 + 25w^2 + 15wy + 22y + 10w24 
15wy should have been 35wy
