What is the solution of x^2 - 8x + 16 = 0?

{4, 8}
{-4, 8}
{-8, 4}
{-2, 4}

The correct answer is: {4, 8}

The solution of this quadratic equation can be found by factoring or using the quadratic formula. In this case, the equation can be factored into (x-4)^2 = 0 which results in x = 4. Therefore, the solution set is {4}. Option B is incorrect because -4 does not satisfy the equation. Option C is incorrect because -8 does not satisfy the equation. Option D is incorrect because -2 does not satisfy the equation.
