Find the roots of the equation x^2 + 2x + 1 = 0

-1, -1
-1, 1
0, -1
0, 1

The correct answer is: -1, 1

The equation x^2 + 2x + 1 can be factored as (x+1)(x+1) = 0. Since two identical factors are multiplied to get zero, there is only one solution, which is x = -1. Therefore, the correct answer is B, with both roots being -1. The other options are incorrect because they do not account for the repeated root of -1. Choice A and C only list one root, while D lists two distinct roots that are not solutions to the equation.
