Answer 2

To simplify the expression (2x-1)+(2x+1)(2x-1), follow these steps:

Step 1: Distribute (2x+1) into (2x-1): (2x+1)(2x-1) = 2x * 2x + 2x * (-1) + 1 * 2x + 1 * (-1) = 4x^2 - 2x + 2x - 1 = 4x^2 - 1

Step 2: Now the original expression becomes: (2x-1) + (4x^2 - 1)

Step 3: Combine like terms: (2x + 4x^2) + (-1 - 1) = 4x^2 + 2x - 2

The simplified expression is 4x^2 + 2x - 2.
