0 = 12.03 * t + 1/2 * −9.8 * t²
0 = 12.03 t − 4.9 t²
0 = t (12.03 − 4.9 t)
t = 0
t = 1203/490 ≈ 2.4551

It's a quadratic equation, so use any method available to solve it. Factoring and completing the square usually work well.
-(½)9.8t² + 12.03t = 0 <--- Because there is no constant term, one solution will be {t=0}
4.9t = 12.03
t = 12.03/4.9
t ≈ 2.46 <--- This is the second solution

0 = 12.03t + [(1/2) x (-9.8) x t²]
This IS your questions right?
0 = 12.03t - 4.9t²
0 = -t(4.9t - 12.03)
t = 0, 12.03/4,9
t = 0, 1203/490
