All real numbers except c = 0 and c = 3.

Explanation:

The equation is:

$\dfrac{1}{c-3}-\dfrac{1}{c}=\dfrac{3}{c(c-3)}$

Since c - 3, c, and c(c - 3) are he denominators, none of them can be equal to zero:

c ≠ 0c - 3 ≠ 0 ⇒ c ≠ 3c (c - 3) ≠ 0 ⇒ c ≠ 0 and c ≠ 3.

Now you can multiply both sides of the equation by the common denominator: c (c - 3):

$c-(c-3)=3\\\\c-c+3=3\\\\0=3-3\\\\0=0$

That means the equality is valid for all real numbers for which it is defined, which is all real numbers except c = 0 and c = 3.
