Q. If , use synthetic division to find .
- Write Coefficients and Value: To use synthetic division, we first write down the coefficients of the polynomial: , , and . Then we write the value we are evaluating, which is , to the left.
- Bring Down First Coefficient: We bring down the first coefficient, , as it is.
- Multiply and Write Result: Multiply the value we brought down by (the value we are evaluating at) and write the result under the second coefficient. So, .
- Add Second Coefficient: Add the second coefficient () to the result from the previous step () and write the sum under it. So, .
- Multiply and Write Result: Multiply the result from the previous step () by and write the result under the third coefficient. So, .
- Add Third Coefficient: Add the third coefficient () to the result from the previous step () and write the sum under it. So, .
