  • Hope you could understand.

    If you have any query, feel free to ask.

  • 2x² - 4x - 2 = 0                  <=>    2(x² - 2x - 1 ) = 0

    <=>  2(x² - 2.x.1 - 1² ) = 0    <=>  2(x - 1)² = 0

    <=>  (x - 1)² = 0/2 = 0          <=>  x - 1 = 0

    <=>  x = 0 + 1 = 1

    P/s: A² - 2AB + B² = (A - B)²

    ANSWER: x = 1

    Ok done. Thank to me :>
