Multiply every term by the LCD of 

  

Cancel away the denominators:

  

   9(w-1)(w-2) + 2(w-2) = -4(w-1)
9(w˛ - 3w + 2) + 2w - 4 = -4w + 4

9w˛ - 27w + 18 + 2w - 4 = -4w + 4

         9w˛ - 25w + 14 = -4w + 4

         9w˛ - 21w + 10 = 0   <--- you got here and couldn't factor.

Use trial and error. The only ways to factor 9 is 9*1 and 3*3,
The only ways to factor 10 is 10*1 and 5*2

           (3w-5)(3w-2) = 0

       3w - 5 = 0;  3w - 2 = 0
           3w = 5;      3w = 2
            w = ;       w =
