Answer:
Step-by-step explanation:
(t - 6)^2 = t^2 - 12t + 36
(t + 6)^2 = t^2 + 12t +36
(t - 6)^2 - (t + 6) = t^2 - 12t + 36 - (t^2 + 12t + 36)
(t - 6)^2 - (t + 6) = t^2 - 12t + 36 - t^2 - 12t - 36
(t - 6)^2 - (t + 6) = -24t The other 4 terms cancel out.
-24t = 0 Divide by - 24
t = 0
There is one root.
