Q. If , use synthetic division to find .
- Write Coefficients and Divisor: To use synthetic division, we first write down the coefficients of the polynomial , which are , , and . Then we write the number we are dividing by, which is , to the left.
- Bring Down First Coefficient: We bring down the first coefficient, which is , and write it below the line.
- Multiply and Write Result: Multiply the number we brought down () by and write the result () under the next coefficient ().
- Add Second Column: Add the numbers in the second column to get and write this number below the line.
- Multiply and Write Result: Multiply the number we just wrote by and write the result under the next coefficient .
- Add Third Column: Add the numbers in the third column () to get and write this number below the line.
