Edwin's solution:
answer:
By inserting the term 0t2 and using long division
or synthetic division.
Do you understand long division or synthetic division?
If not post again asking how we get the following:
t2 + 4t - 3
---------------------
t - 4 ) t3 - 0t2 - 19t + 9
t3 - 4t2
--------
4t2 - 19t
4t2 - 16t
---------
3t + 9
3t + 12
--------
-3
Answer: t2 + 4t - 3 r=-3
Or by synthetic division:
4 | 1 0 -19 9
| 4 16 -12
---------------
1 4 -3 -3
Answer: t2 + 4t - 3 r=-3
Or if you know to put the remainder over the dividend:
Answer: or
