    x=-3 x=2

    Step-by-step explanation:

    x² + x = 6

    Subtract 6 from each side

    x² + x - 6 = 6-6

    x² + x - 6=0

    Factor

    What 2 numbers will multiply to - 6 and add to 1

    3 * -2 = - 6

    3+-2 = 1

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

    Using the zero product property

    x+3 = 0 x-2=0

    x=-3 x=2
