Answer:
C.
Explanation:
Consider the numerator;
When (x - 3)(x - 4) = 0
x = 3 or x = 4.
When x > 3 and < 4 (x - 3)(x- 4) will be negative and the denominator (x - 5(x + 6)^2 will be negative so the function will be positive.
So 3 < x < 4 is a part of the answer.
When x > 5 the denominator will be positive and so will be the numerator.
So x > 5 also is a solution.
When x < 3 the numerator will be positive and the denominator will be negative so the function will be negative.
