Synthetic Division ಅನ್ನು ಹೇಗೆ ಲೆಕ್ಕ ಹಾಕುವುದು
Synthetic Division ಎಂದರೇನು?
Synthetic division is a shorthand method for dividing a polynomial by a linear factor (x − r). It is faster than long division and directly tests whether r is a root of the polynomial.

Divide polynomial P(x) by (x − c) using a simplified algorithm avoiding long division
- P(x)
- polynomial to divide
- (x − c)
- linear divisor
- c
- value
ಹಂತ-ಹಂತದ ಮಾರ್ಗದರ್ಶಿ
- 1Write coefficients in a row
- 2Drop first coefficient; multiply by root r
- 3Add to next coefficient; repeat
- 4Last value is remainder; others are quotient coefficients
Worked Examples
ಇನ್ಪುಟ್
x³−6x²+11x−6 ÷ (x−1)
ಫಲಿತಾಂಶ
Quotient: x²−5x+6, Remainder: 0 (so x=1 is a root)
ಇನ್ಪುಟ್
x³+2x−3 ÷ (x−1)
ಫಲಿತಾಂಶ
Quotient: x²+x+3, Remainder: 0
Frequently Asked Questions
When is synthetic division useful?
Quick division by linear factors, finding polynomial values via Remainder Theorem, and factoring.
Can synthetic division be used for non-linear divisors?
No, synthetic division only works for divisors of the form (x − c). Use long division otherwise.
What is the Remainder Theorem?
When P(x) is divided by (x − c), remainder = P(c).
