Answer:

A:x=3

B:x=-4

Explanation:

The domain is set of all values of x for which the given rational function is defined.

The rational equation is


(50)/(4x - 12) + \frac{x - 4}{ {x}^(2) + x - 12 } = (x)/(2)

The rational function will not be defined if the denominator is zero.

That is if:

1.


4x - 12 = 0 \implies 4x = 12\implies \: x = 3

2.


{x}^(2) + x - 12 = 0\implies (x - 3)(x + 4)

This implies that x=3 or x =-4

Therefore the equation is defined on all real values of x, except x=3 or-4
