Start by factoring out a 5 from each term. What do you come up with?

i got 5(w^27w+12)=0...is that right?..and then do i factor the middle?...but when i did i get 3 answers

Yes, that's good.
You're going to want something in the form (__ + __)(__ + __)
One or both of the signs could be negative, though.
Look at the 12. What are its two closest factors? When added, do they equal 7?
You can check yourself by using the FOIL method after you come up with your factorization. Now, what do you get?
