Answer :

Sure, let's solve and simplify the given expression step-by-step.

Given the expression:

[tex]\[ \frac{2x - 1 - 4ax + 2a}{2x^2 - x} \][/tex]

First, we'll simplify the numerator and the denominator separately where possible.

### Step 1: Simplify the numerator

The numerator is:

[tex]\[ 2x - 1 - 4ax + 2a \][/tex]

Group the terms involving [tex]\(x\)[/tex] together in the numerator:

[tex]\[ (2x - 4ax) + (-1 + 2a) \][/tex]

Factor [tex]\(x\)[/tex] out from the first group:

[tex]\[ 2x(1 - 2a) + (-1 + 2a) \][/tex]

So, the numerator simplifies to:

[tex]\[ 2x(1 - 2a) + (-1 + 2a) \][/tex]

### Step 2: Simplify the denominator

The denominator is:

[tex]\[ 2x^2 - x \][/tex]

Factor out [tex]\(x\)[/tex] from the denominator:

[tex]\[ x(2x - 1) \][/tex]

### Step 3: Combine and simplify the expression

Putting the simplified numerator and denominator together:

[tex]\[ \frac{2x(1 - 2a) + (-1 + 2a)}{x(2x - 1)} \][/tex]

To simplify this expression, we need to separate the terms in the numerator and then try to cancel common factors. Split the fraction:

[tex]\[ = \frac{2x(1 - 2a)}{x(2x - 1)} + \frac{-1 + 2a}{x(2x - 1)} \][/tex]

We can cancel [tex]\(x\)[/tex] in the first term of the numerator and the denominator:

[tex]\[ = \frac{2(1 - 2a)}{2x - 1} + \frac{-1 + 2a}{x(2x - 1)} \][/tex]

Now observe that both parts individually do not share any further common factors, thus the final simplified version of the expression is:

[tex]\[ \frac{1 - 2a}{x} \][/tex]

Hence, the expression simplifies to:

[tex]\[ \frac{1 - 2a}{x} \][/tex]
