Study Notes
Synthetic Division
- Shorter method for dividing polynomials by linear factors of the form (x - k)
- More efficient than long division
Steps for Synthetic Division
- Write coefficients of the dividend in a row.
- Write the value of k (from the divisor x - k) to the left
- Bring down the leading coefficient (the first coefficient)
- Multiply the number in the bottom row by k
- Add the result to the corresponding coefficient in the top row
- Repeat for each remaining coefficient
- Bottom row numbers are the coefficients of the quotient
- The last number is the remainder
