Question

    Solve the equation: 2x┬▓ - 8x + 6 =

    0.
    A x = 1, x = 3 Correct Answer Incorrect Answer
    B x = 2, x = 3 Correct Answer Incorrect Answer
    C x = 3, x = 1 Correct Answer Incorrect Answer
    D x = 4, x = 6 Correct Answer Incorrect Answer

    Solution

    Using the quadratic formula: x = [-b ┬▒ тИЪ(b┬▓ - 4ac)] / 2a Here, a = 2, b = -8, c = 6. Discriminant = (-8)┬▓ - 4 ├Ч 2 ├Ч 6 = 64 - 48 = 16. Roots: x = [8 ┬▒ тИЪ16] / 4 = [8 ┬▒ 4] / 4. Thus, x = 3 or x = 1. Correct Answer: a) x = 1, x = 3.
