Key Topics to Revise

1

Variables, Constants, and Basic Concepts

  • Variable: A literal number that can have different values (usually x, y, z)
  • Constant: A literal number with a fixed value (usually a, b, c)
  • Algebraic expression: Combination of numbers, variables, and arithmetical operations
2

Polynomials: Definition and Types

  • Polynomial: Algebraic expression where variables don't appear in denominators, exponents are whole numbers
  • Standard form: a₀ + a₁x + a₂x² + ... + aₙxⁿ
  • Monomial: 1 term (e.g., 5x²), Binomial: 2 terms (e.g., 3x + 2), Trinomial: 3 terms (e.g., x² + 2x + 1)
3

Degree of Polynomials

  • Degree of a term: Sum of exponents of all variables in that term
  • Degree of polynomial: Highest degree among all terms with non-zero coefficients
  • Degree of constant polynomial ≠ 0 is 0
4

Evaluation and Zeros of Polynomials

  • Evaluation: Substitute given value(s) for variable(s) and simplify
  • Zero of polynomial: Value of variable that makes polynomial equal to zero
  • If P(a) = 0, then x = a is a zero of polynomial P(x)
