Key Topics to Revise

1

Introduction to Polynomials

  • A polynomial is an algebraic expression with variables having whole number exponents only
  • Polynomials contain terms with variables, coefficients, and constants
  • The general form is: p(x) = aₙxⁿ + aₙ₋₁xⁿ⁻¹ + ... + a₁x + a₀
2

Classification of Polynomials

  • Polynomials are classified by number of terms and degree
  • By terms: Monomial (1 term), Binomial (2 terms), Trinomial (3 terms)
  • By degree: Linear (degree 1), Quadratic (degree 2), Cubic (degree 3)
3

Zeros of Polynomials

  • Zero of polynomial p(x) is value 'a' such that p(a) = 0
  • Linear polynomials have exactly one zero
  • Zero of polynomial corresponds to x-intercept of its graph
4

Remainder Theorem and Factor Theorem

  • Remainder Theorem: When p(x) is divided by (x-a), remainder is p(a)
  • Factor Theorem: (x-a) is factor of p(x) if and only if p(a) = 0
  • These theorems connect polynomial division with evaluation
