**Does it bother you that in the problem above, using the quadratic formula, we solved for t and not x?**

Maybe it did, and maybe it didn't. It does tend to make some students uncomfortable, at least at first.

The quadratic formula is often presented as:

This corresponds to the standard form of the quadratic equation **ax**^{2} + bx + c = 0, where a, b and c are constants, for which we hope to find the value of x.
