1 Jawaban

  • Nomor 1
    = | √2 - 1 |
    = (√2 - 1)²
    = (√2 - 1)(√2 - 1)
    = 2 - 2√2 + 1
    = 3 - 2√2

    Nomor 2
    = | 3 - (-21) |
    = (3 - (-21)²
    = (3+21)²
    = 24²
    = 576

    Nomor 3
    = | -2x + 3 |
    = (-2x + 3)²
    = (-2x + 3)(-2x + 3)
    = 4x² - 12x + 9

    Nomor 4
    = | ½ x - ⅔ |
    = (½ x - ⅔)²
    = (½ x - ⅔)(½ x - ⅔)
    = ¼ x² - ⅓ x - ⅓ x + 4/9
    = ¼ x² - ⅔ x + 4/9

    semoga berguna +_+
