Question:

If a + b + c = 3 and a = b = c ≠ 1

Find \(\frac{1}{(1 - a) (1 - b)}\) + \(\frac{1}{(1 - b) (1 - c)}\) + \(\frac{1}{(1 - c) (1 - a)}\)

Options:

3

6

1

0

Correct Answer:

0

Explanation:

Here one equation and three variables are given

So, put any two = 0

b = c = 0

a + 0 + 0 = 3

a = 3 (put in find)

\(\frac{1}{(1 - 3) (1 - 0)}\) + \(\frac{1}{(1 - 0) (1 - 0)}\) + \(\frac{1}{(1 - 0) (1 - 3)}\)

- \(\frac{1}{2}\) + 1 - \(\frac{1}{2}\) = 0
