    x=2 x=3

    Step-by-step explanation:

    log4 (x^2 + 6) = log4 5x

    Since the bases are the same, we can set

    x^2 + 6 = 5x

    Subtract 5x from each side

    x^2 - 5x + 6 = 5x-5x

    x^2 - 5x + 6 = 0

    Factor

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

    Using the zero product property

    x-3=0 x-2=0

    x=3 x=2
