+491 1. Show that the answer when simplifying the following expression: 2x-8 / x^2-6x+8 has the same value when x = 0. Explain how this is helpful
+37146 2(x-4) / ( x-4)(x-2)
2/(x-2) when x = 0 2/-2 = -1
Substitute '0' for x in the original equation
-8/8 = -1 Yup, they are equal 
It is helpful because it 'simplifies' the calculation(s) involved.....there are less chance for errors.
