Question

The roots of the quadratic equation \(x^2 - 4x + 4 = 0\) are:

• A. 4, 1
• B. 2, 2
• C. -2, -2
• D. 4, 2

Hint:

If a quadratic equation is a perfect square, such as \((x - a)^2 = 0\), it has a repeated root, which is \(x = a\).

Answer 1

The Correct Option is B

The quadratic equation \(x^2 - 4x + 4 = 0\) can be factored as: \[ (x - 2)(x - 2) = 0 \] Thus, the roots are \(x = 2\) and \(x = 2\). Therefore, the correct answer is option (2).
