To subtract the given expressions, we need to find a common denominator. The common denominator for the three fractions is (x-6)(x+6)(6-x^2).

Next, we multiply each fraction by the appropriate factors to obtain the common denominator.

For the first fraction, we multiply the numerator and denominator by (x+6)(6-x^2). For the second fraction, we multiply the numerator and denominator by (x-6)(6-x^2). For the third fraction, we multiply the numerator and denominator by (x-6)(x+6).

After multiplying, we simplify the numerators and combine like terms.

The resulting expression is:

[(x+6)(6-x^2) - 3(x-6)(6-x^2) + 3x(x-6)(x+6)] / [(x-6)(x+6)(6-x^2)]
