Key Topics to Revise

1

Introduction to Polynomials

  • A polynomial is an algebraic expression with variables having whole number exponents only
  • Variables are denoted by letters like x, y, z and can take any real value
  • Constants (a, b, c) have fixed values throughout a problem
2

Types of Polynomials

  • Monomial: Polynomial with only one term (e.g., 5x³, -2x, 7)
  • Binomial: Polynomial with exactly two terms (e.g., x² + 3, 2x - 5)
  • Trinomial: Polynomial with exactly three terms (e.g., x² + 2x + 1)
3

Zeros of a Polynomial

  • Zero of polynomial p(x) is a number 'a' such that p(a) = 0
  • Finding zeros involves solving p(x) = 0
  • Linear polynomial has exactly one zero: x = -b/a for ax + b
4

Remainder and Factor Theorems

  • Remainder Theorem: When p(x) is divided by (x - a), remainder = p(a)
  • Factor Theorem: (x - a) is factor of p(x) if and only if p(a) = 0
  • These theorems provide shortcuts for division and factorization
