w^2 plus 14 over w^2-2w-3.
find all numbers for the rational is undefined?
---------------------
Factor the denominator.
w^-2w-3 = (w-3)(w+1)
-----
The rational expression is undefined for w = 3 and for w = -1.

Hi,



%28w%5E2+%2B14%29%2F%28w%5E2-2w-3%29



%28w%5E2+%2B14%29%2F%28%28w-3%29%28w%2B1%29%29%29

find all numbers for which the rational expression is undefined

A rational expression is undefined whenever the dnominator is equal to zero

w = 3 or w = -1  would cause the denominator in this expression to = 0

w = 3 or w = -1 would make this rational expression undefined
