Your answers are right sir ! but how is 12i=3i-6j + c => c= -3i+6j ?????
isnt is supposed to be 9i+6j?
astarmathsandphysics:
Now I get 9i+18j after checking

I got the same at first , but i checked the answer at the back it was exactly like this
( 3t(sq) + 9) i + ( 4t(cubed) -10t + 6 ) j
Very weird book !!!!
anyway thanks a million for your answers and explanations ! + rep!
astarmathsandphysics:
BOOK is correct!!!
When I did it the first time I ignored the 12i
and the second time I got 12i+6j=18j
