Step 1.1

Split the limit using the Sum of Limits Rule on the limit as $x$ approaches $0.5$ .

$\frac{lim_{x \to 0.5} 2 x - lim_{x \to 0.5} 1}{| 2 x^{3} - x^{2} |}$

Step 1.2

Move the term $2$ outside of the limit because it is constant with respect to $x$ .

$\frac{2 lim_{x \to 0.5} x - lim_{x \to 0.5} 1}{| 2 x^{3} - x^{2} |}$

Step 1.3

Evaluate the limit of $1$ which is constant as $x$ approaches $0.5$ .

$\frac{2 lim_{x \to 0.5} x - 1 \cdot 1}{| 2 x^{3} - x^{2} |}$

Step 2

Evaluate the limit of $x$ by plugging in $0.5$ for $x$ .

$\frac{2 \cdot 0.5 - 1 \cdot 1}{| 2 x^{3} - x^{2} |}$
