Explanation:

The expression


(x + (1)/(3x + 12))

is defined for all real values of (x) except when the denominator ( 3x + 12 ) equals zero because division by zero is undefined.

So, to find the values of (x) for which the expression is defined, set the denominator (3x + 12) not equal to zero and solve for (x):


\[3x + 12 \\eq 0\]</p><p>\[3x \\eq -12\]</p><p>\[x \\eq -4\]

Therefore, the expression


(x + (1)/(3x + 12))

is defined for all real values of (x) except (x = -4).
