Two flares are launched from a life raft. The height h of the first flare in metres above the sea is modelled by the formula h1= t2+t+1meters,and the second flare is h2=4-t where t is the time

12 in seconds after the flare is launched. Determine
(i) Time taken and
(ii) Height when the two flares meet each other.
Hint: When two flares meet each other, their heights are the same (h1=h2).
