Answer :
Answer:
t = ± 4
Step-by-step explanation:
-16t^2+256=0
Subtract 256 from each side.
-16t^2+256-256=0-256
-16t^2=-256
Divide each side by -16.
-16 t^2/-16 = -256/-16
t^2 = 16
Take the square root of each side.
sqrt(t^2) = ±sqrt(16)
t = ± 4
Answer:
t = ± 4
Step-by-step explanation:
-16t^2+256=0
Subtract 256 from each side.
-16t^2+256-256=0-256
-16t^2=-256
Divide each side by -16.
-16 t^2/-16 = -256/-16
t^2 = 16
Take the square root of each side.
sqrt(t^2) = ±sqrt(16)
t = ± 4
