Final answer:

To solve the equation 2sin(x)cos(x) - sin(x) - 2cos(x) = 1, first factor out sin(x), then divide both sides by 2cos(x) - 1, simplify using trigonometric identities, and rearrange the terms to get a quadratic equation sin(2x) - 2cos(x) - 1 = 0.

Step-by-step explanation:

To solve the equation 2sin(x)cos(x) - sin(x) - 2cos(x) = 1, we can use trigonometric identities and algebraic manipulation.

1. Start by factoring out sin(x) from the equation: sin(x)(2cos(x) - 1) - 2cos(x) = 1.

2. Divide both sides of the equation by 2cos(x) - 1: sin(x) - 2cos(x) / (2cos(x) - 1) = 1 / (2cos(x) - 1).

3. Simplify the equation using the fact that 2sin(x)cos(x) = sin(2x): sin(2x) - 2cos(x) / (2cos(x) - 1) = 1 / (2cos(x) - 1).

4. Multiply both sides of the equation by (2cos(x) - 1): sin(2x) - 2cos(x) = 1.

5. Rearrange the terms to get a quadratic equation: sin(2x) - 2cos(x) - 1 = 0.

6. Use trigonometric identities to simplify the equation further.
