    x1, x2 = 7.73, 4.27

    Step-by-step explanation:

    To find the roots of a quadratic function we have to use the bhaskara formula

    ax^2 + bx + c

    x^2 - 12x + 33

    a = 1 b = - 12 c = 33

    x1 = (-b + √ b^2 - 4ac) / 2a

    x2 = (-b - √ b^2 - 4ac) / 2a

    x1 = (12 + √ (-12^2 - (4 * 1 * 33))) / 2 * 1

    x1 = (12 + √ (144 - 132)) / 2

    x1 = (12 + √12) / 2

    x1 = (12 + 3.46) / 2

    x1 = 15.46 / 2

    x1 = 7.73

    x2 = (12 - √ (-12^2 - (4 * 1 * 33))) / 2 * 1

    x2 = (12 - √ (144 - 132)) / 2

    x2 = (12 - √12) / 2

    x2 = (12 - 3.46) / 2

    x2 = 8.54 / 2

    x2 = 4.27
