Logv3(12) = logv3 (3t^2) - logv3 (3t)

(the v means "log 3"- 3 is the base)

    remember to divide the terms when subtracting in logarithms.

    WAIT ITS t^2 NOT 3t^2

    ok, divide throughout by logv3 and then you will get a quadratic equation and solve for t.

    But then when i try to factor i get 0=t^2-3t-12
