To solve the equation x / (2x + 1) + (1 / 4) = 2 / (2x + 1) and find any extraneous solutions, follow these steps:

Start by multiplying both sides of the equation by the common denominator, which is (2x + 1) * 4. This will eliminate the fractions.

After multiplying, simplify the equation and combine like terms.

Solve the resulting equation for x.

Check the solutions obtained by substituting them back into the original equation to identify any extraneous solutions.
