    x=3, x=9

    Step-by-step explanation:

    2x^2 - 24x + 54 = 0

    1. Divide both sides of the equation by 2

    x^2 - 12x + 27 = 0

    2. Write - 12x as a difference

    x^2 - 3x - 9x + 27 = 0

    3. Factor out x from the expression, then factor out - 9 from the expression

    x * (x - 3) - 9 (x - 3) = 0

    4. Factor out x - 3 from the expression

    (x - 3) * (x - 9) = 0

    5. When the product of factors equals 0, at least one factor is 0

    x - 3 = 0

    x - 9 = 0

    6. Solve the equation for x

    x=3

    x=9
