B Correct answer
Explanation

2a - 2 = 4 - 4a => 6a = 6 => a = 1. The only root is 1, not -1. Thus, the statement is false.

AI explanation

The given equation 2a - 2 = 4 - 4a is a linear equation, meaning it only has one root. Solving for a, we combine the terms by adding 4a to both sides and adding 2 to both sides to get 6a = 6. Dividing by 6 gives a = 1. Since a linear equation only has the single root of 1, the statement claiming the roots are 1 and -1 is false.
