    Step-by-step explanation:

    hello:

    9x² - 12x + 4 = 0

    a=9 b=-12 c = 4

    delta = b²-4ac

    delta = (-12) ² - 4 (9) (4) = 144 - 144 = 0

    single solution x = - b/2a = - (-12) / 18 = 12/18 = 2/3

    x = 2/3

    Step-by-step explanation:

    9x2-12x+4=0

    Step 1: Factor left side of equation.

    (3x-2) (3x-2) = 0

    Step 2: Set factors equal to 0.

    3x-2=0 or 3x-2=0

    x = 2 / 3
