You have a quadratic equation in $t$. If you can't factor it, you can use the equation for the roots of a quadratic equation (which is obtained by completing the square).

As it's a quadratic equation, there are usually two solutions. Often, only one is relevant, but problems are sometimes set where both solutions are relevant.
