Plz ! i’m rly stuck on this question.

C

Step-by-step explanation:

Rearrange the quadratic into standard form by subtracting d from both sides

- 16t² + 8t - d = 0 ← in standard form

with a = - 16, b = 8, c = - d

Using the quadratic formula to solve for t

t = (- 8 ± )/ - 32

 = ( - 8 ± )/ - 32

  = ( - 8 ± ) / - 32

  = ( - 8 ± 8) / - 32

  = ±

  = ±

  = ±

answer: a and b
