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. This process is similar to traditional long division used with numbers. The main goal is to find a quotient and a remainder. It helps solve problems in algebra that involve polynomials, making it an essential skill for students and anyone working with equations.
