Introduction to Polynomials

  • A polynomial is an algebraic expression where all powers of variables are whole numbers (0, 1, 2, 3, ...)
  • Examples: x³ + 2x² + 5, 3y² - 7y + 1, 5 (constant polynomial)
  • Non-polynomials: √x + 5, 1/x - 3, x^(-2) + 1 (powers are not whole numbers)
2

Degree of Polynomials

  • For one variable: Degree = highest power of the variable
  • For multiple variables: Degree = highest sum of powers in any term
  • Degree of non-zero constant polynomial = 0
3

Forms of Polynomials

  • Standard form: Terms arranged in descending order of powers
  • Index form: All missing terms included with coefficient 0
  • Coefficient form: Only coefficients written in order
4

Operations on Polynomials

  • Addition/Subtraction: Combine like terms (same power)
  • Multiplication: Use distributive property and laws of indices
  • Division: Use long division or synthetic division method
