Question

All I've found is 1 but how do I work that out properly beaides guess and check​

Answer 1

1

Explanation:

(1-x)/x=0

or, 1-x=0

or, -x=-1

or, x=1

Answer 2

F(x) = 0 when x=1

Explanation:

We need the numerator to equal zero

1-x = 0

Add x to each side

1-x+x = 0+x

1 =x

The denominator cannot equal zero( The denominator does not equal zero when x =1)

F(x) = 0 when x=1
