- Synthetic Division
- By the way, this different method to do long division is called synthetic division.
- -4
- The equation given is 2x^3+6x^2+10 by x+4. To do this, you must put the equation in a little T-table formation
- 2 6 0 10
- After doing this, you bring down the 2. Once you bring that down, you multiply the 2 by -4. By doing this you will get -8. Afterwards you subtract the 6 and -8 to get -2, as shown
- -4
- 2 6 0 10
- Now your probably wondering where the 0 came from. Since the equation doesn't have a third x variable we add zero so that we can still solve. After getting -2, you multiple -2 by -4, which is 8. After getting 8 you subtract with 0 to get 8. And lastly you multiply 8 with -4 to get -32 which you will subtract from 10 to get your final answer.
- -4
- 2 6 0 10
- After doing this, all you do is put the new answer in the correct form and your done. Now I want everyone to try to do it themselves.
- 2x^2-2x+8 with remainder -3
- YAY!
- Hey Mrs, I did the question can you check if it is correct.
- 2x^2-2x+8 with remainder -3
- Good job Jasmine, this is perfect. Keep up the good work!
