You can factor out a 3t first, resulting in:

Now, let's factor the equation in the middle using the quadratic equation. Plug in the values to the quadratic equation:

Simplify, you get your
x's:

To write the equation in simplified form, you just write it this way:
That's your answer ^
71 is the answer. If you round it, it would be 70.
