Thanks for any help!

w^2-5w-24=0
(w-8)(w+3) = 0
w = 8 or w = -3
(w-8)(w+3) = 0
w = 8 or w = -3

w^2-5w-24= (w + ?)(w +?)
Now, let's see -- the 2 ?'s need to mult. to - 24, but add to -5.
So, 1 of those ?'s is +, the other neg. If they add to a neg., the the neg ? must be bigger.
Factors of 24: 1,2,3,4,6,8,12,24. Pick two of these that are 5 apart. There you are! Just set them = to 0. List them in order if your instructor requires that.

( w - 8 ) ( w + 3 ) = 0
So w = 8 , and w = -3.
So w = 8 , and w = -3.
