    Step-by-step explanation:

     {x}^{2}  - 18 x+ 81\\  \\  = {x}^{2}  - 9x - 9x + 81 \\  \\  = x(x - 9) - 9(x - 9) \\  \\ =  (x - 9)( x- 9)  \\  \\  = (x - 9) ^{2}

    _____________________________________

    x – 9 = 0

    → x = 9

    …………………………………………………………

    x – 9 = 0

    → x = 9

    ………………………………………………………..

    x = 9 , 9

    HOPE IT HELPS YOU
