The given expression is:

$\frac{4x^2 - 12x - 24}{4x}$

Step-by-Step Simplification:

1. Factor the numerator: The numerator is $4x^2 - 12x - 24$. First, we can factor out a common factor of $4$ from the terms: $4(x^2 - 3x - 6)$

2. Rewrite the expression: Now the expression becomes: $\frac{4(x^2 - 3x - 6)}{4x}$

3. Cancel the common factor: The $4$'s in the numerator and denominator cancel out: $\frac{x^2 - 3x - 6}{x}$

4. Simplify the remaining expression: Now, divide each term in the numerator by $x$: $\frac{x^2}{x} - \frac{3x}{x} - \frac{6}{x} = x - 3 - \frac{6}{x}$

Thus, the simplified expression in standard form is:

$x - 3 - \frac{6}{x}$
