$t = \frac{- 1 \pm \sqrt{1 - 24 \cdot 0}}{2 \cdot 6}$

Step 4.1.2.2

Multiply $- 24$ by $0$ .

$t = \frac{- 1 \pm \sqrt{1 + 0}}{2 \cdot 6}$

Step 4.1.3

Add $1$ and $0$ .

$t = \frac{- 1 \pm \sqrt{1}}{2 \cdot 6}$

Step 4.1.4

Any root of $1$ is $1$ .

$t = \frac{- 1 \pm 1}{2 \cdot 6}$

Step 4.2

Multiply $2$ by $6$ .

$t = \frac{- 1 \pm 1}{12}$

Step 5

The final answer is the combination of both solutions.

$t = 0, - \frac{1}{6}$
