\frac{x}{2 x - 1} \cdot (4 (2 x - 1))

$\frac{x}{2 x - 1} \cdot (4 (2 x - 1))$

Step 1

Remove parentheses.

\frac{x}{2 x - 1} \cdot (4 (2 x - 1))

$\frac{x}{2 x - 1} \cdot (4 (2 x - 1))$

Step 2

Apply the distributive property.

\frac{x}{2 x - 1} \cdot (4 (2 x)) + 4 \cdot - 1

$\frac{x}{2 x - 1} \cdot (4 (2 x)) + 4 \cdot - 1$

$2$ by

4

$4$ .

\frac{x}{2 x - 1} \cdot (8 x) + 4 \cdot - 1

$\frac{x}{2 x - 1} \cdot (8 x) + 4 \cdot - 1$

Step 3.2

Multiply

4

$4$ by

- 1

$- 1$ .

\frac{x}{2 x - 1} \cdot (8 x) - 4

$\frac{x}{2 x - 1} \cdot (8 x) - 4$

\frac{x}{2 x - 1} \cdot (8 x) - 4

$\frac{x}{2 x - 1} \cdot (8 x) - 4$

Step 4

Finding the LCD of a list of values is the same as finding the LCM of the denominators of those values.

2 x - 1, 1, 1

$2 x - 1, 1, 1$

Step 5

Remove parentheses.

2 x - 1, 1, 1

$2 x - 1, 1, 1$

Step 6

The LCM of one and any expression is the expression.

2 x - 1

$2 x - 1$
