F(x) = 8/x and g(x) = 8/x
To find f(g(x)), all you do is substitute g(x) into the x value of f(x).
So f(g(x)) = 8/(8/x) which = x
Similarly g(f(x)) is found by substituting f(x) into the x value of g(x)
g(f(x)) = 8/(8/x) which = x
If the polynomial is of the form x^2+bx+c (ie., no factor in front of the x^2!!) then you can look for numbers that add up to b and multiply to c.
So in this case: what two numbers, when added, give -2 and when multiplied, give 1? A little trial and error gives you -1 and -1.
So the factorization is (x-1)(x-1). This is zero for x=1. There is only one zero.
