How many extraneous solutions does the equation below have?

(2m) / (2m+3) - (2m) / (2m-3) = 1

0

1

2

3

In the given operation,

2m / (2m+3) - 2m / (2m-3)

We can get the answer by performing the operation by multiplying the denominator giving us a fraction with a denominator of,

(2m + 3) (2m - 3)

The denominator cannot be equal to zero. Therefore it should not be equal to,

m cannot be equal to - 3/2 and 3/2

The answer is 2, the third choice.
