w^211w+30=0

If you have to factor this, start with:
(w )(w )
Then you need two factors that when ADDED together gives you 11, and when multiplied together gives you 30. Can you come up with these factors? 
To get the factors, find two numbers that will multiply to get 30 and add to get 11.
I hope this helps a little more. Thanks for asking.
