About Polynomial Long Division

Polynomial long division is a method for dividing one polynomial by another, resulting in a quotient polynomial and a remainder polynomial.

Division Formula:

P(x) = D(x) × Q(x) + R(x)

Where:

  • P(x) is the dividend (numerator)
  • D(x) is the divisor (denominator)
  • Q(x) is the quotient
  • R(x) is the remainder

The degree of R(x) is always less than the degree of D(x).

Applications:
  • Finding Roots: Helps in finding roots of polynomials using the Remainder Theorem
  • Partial Fraction Decomposition: Essential for integrating rational functions
  • Polynomial Factorisation: Assists in factoring polynomials by testing possible factors
  • Algebraic Simplification: Simplifies complex rational expressions

Understanding Polynomial Long Division

Polynomial long division is a method used to divide one polynomial by another. Just like long division with numbers, this process helps you break down complex polynomials into simpler parts. The result of this division is a quotient and a remainder, which provides insight into the relationship between the two polynomials. This is especially useful in algebra and Calculus for simplifying expressions and solving equations.
