**Michael**, Sunday, December 2, 2007 at 8:03pmStart by factoring out a 5 from each term. What do you come up with?

**gabs**, Sunday, December 2, 2007 at 8:05pmi got 5(w^2-7w+12)=0...is that right?..and then do i factor the middle?...but when i did i get 3 answers

**Michael**, Sunday, December 2, 2007 at 8:08pmYes, 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?

**Michael**, Sunday, December 2, 2007 at 8:09pmI should mention that you are ignoring the 5 now and working solely with w^2-7w+12.

**Michael**, Sunday, December 2, 2007 at 8:40pmYou just ignore the 5, as 5 cannot equal 0. Your answers are just w = 3 and w = 4.
