What is Synthetic Division?
Synthetic division is a method of dividing polynomials by linear factors. It is a shortcut to the long division method and is particularly useful when dividing polynomials by factors of the form (x - a) or (x + a). The method involves using a single row of numbers to perform the division, rather than the multiple rows required by the long division method.
How to Perform Synthetic Division
To perform synthetic division, we need to follow these steps:
- Write down the coefficients of the polynomial in a row, with the constant term on the right.
- Write down the value of the linear factor (x - a) or (x + a) that we are dividing by.
- Bring down the first coefficient of the polynomial.
- Multiply the value of the linear factor by the first coefficient and write the result below the second coefficient.
- Add the second coefficient and the result from step 4.
- Multiply the value of the linear factor by the result from step 5 and write the result below the third coefficient.
- Add the third coefficient and the result from step 6.
- Continue this process until we have added all the coefficients.
- The final result is the quotient of the division.
