  • a = 3
    b = 11
    c = -4

    Nilai D = b²-4ac = 11² - 4.3(-4) = 121 +48 = 169

    maka

    x1
    = -b + √D / 2a
    = -11 + √169  / 2.3
    = -11 + 13 / 6
    = 2/6
    = 1/3

    x2
    = -b - √D /2a
    = -11 - √169 / 2.3
    = -11 - 13 / 6
    = -24 / 6
    = -4

    Semoga membantu :)
