let f be defined by f(x)= x-4 and g be defined by g(x )= {(x2 - 16) / (x+4) , x nt eql to -4

α (alpha) , x= -4

find α such that f(x) = g(x) for all x

Plz give the answer of this question

To the viewer -
f(x)  = x - 4
g(x) = (x^2 - 16)/(x + 4)
       = (x + 4)(x - 4) / (x + 4)
       = (x - 4)

Hence, 
f(x) = g(x)

Thus,
f(-4) = g(-4)

So, to find A -
-4 - 4 = A

Hence, for A -
A= -8

(A stands for Alpha 0

Here is the answer

f(x)  = x - 4
g(x) = (x^2 - 16)/(x + 4)
       = (x + 4)(x - 4) / (x + 4)
       = (x - 4)

Hence, 
f(x) = g(x)

Thus,
f(-4) = g(-4)

So, to find A -
-4 - 4 = A

Hence, for A -
A= -8

(A stands for Alpha 0
