To solve the quadratic equation 2t^2 - 5t - 12 = 0 using the quadratic formula, we can use the formula:

t = (-b ± √(b^2 - 4ac)) / (2a)

In this case, a = 2, b = -5, and c = -12.

Plugging in these values into the quadratic formula, we have:

t = (-(-5) ± √((-5)^2 - 4(2)(-12))) / (2(2))
= (5 ± √(25 + 96)) / 4
= (5 ± √121) / 4
= (5 ± 11) / 4

This gives us two solutions:

t1 = (5 + 11) / 4 = 16 / 4 = 4
t2 = (5 - 11) / 4 = -6 / 4 = -3/2

Therefore, the solutions to the equation 2t^2 - 5t - 12 = 0 are t = 4 and t = -3/2.
