    The correct options are,

    x = - 2 and x = 3

    Step-by-step explanation:

    It is given that,

    x² - x - 6 = 0

    To find the solution of given equation

    x² - x - 6 = 0 can be written as

    x² + 2x - 3x - 6 = 0

    x (x + 2) - 3 (x + 2) = =

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

    Either (x + 2) = 0 or (x - 3) = 0

    If (x + 2) = 0 then x = - 2

    If (x - 3) = 0 then x = 3

    Therefore the correct options are,

    x = - 2 and x = 3
