Assuming it is:
right away we can see that it is undefined if c = -5, we get division by 0 in two of the fractions
rewrite this to
simplify
Cancel c-5, c+5 and 3c
=
c = -.5 also makes it undefined

The expression is undefined wherever the denominator of any fraction is zero, BEFORE simplifying. The given expression is
Factor each denominator....
Oberve that the values of c that make any of the denominators equal to 0 are -5, 5, 0, and 1/2.
To simplify, cancel the common factors 3, c, and (c-5) in the numerator of the complex fraction...
... then "flip and multiply":
ANSWER: = ; c not equal to -5, 5, 0, or 1/2
