A Correct answer
Explanation

The equation x^2 - 4x + 4 = 0 factors to (x - 2)^2 = 0. This gives x = 2, x = 2, which are the same roots.

AI explanation

Calculate the discriminant of the equation using b squared minus 4ac, which gives 16 minus 16 equal to 0. Since the discriminant is zero, the quadratic equation has identical real roots given by minus b divided by 2a, which equals 2. Therefore, the statement that the equation has same roots is True.
