H=-16t^2+96t+4solve by factoring
2 answers:
Answer:
t = 3 ± ½√37
Step-by-step explanation:
0 = -16t² + 96t + 4
This isn't factorable, so complete the square or use quadratic formula. Completing the square:
16t² − 96t = 4
t² − 6t = 1/4
t² − 6t + 9 = 1/4 + 9
(t − 3)² = 37/4
t − 3 = ±½√37
t = 3 ± ½√37
