Answer:
Explanation:
alright lets get started.

there are two fractions in subtraction.
We need to make common denominators if we need to subtract these fractions.

Now, we have common denominators so we can subtract the fractions.


We can see, c and (c-3) both are in denominators,
For the expression to be defined, c should not be equals to 0.
Similarly, c-3 should not be equals to 0.
So, c should not be equals to 3.
So, it my have all value of c except c = 0 and c = 3 : answer
Hope it will help :)
