Study Notes

Algebra

What is Algebra?

  • A branch of mathematics that deals with variables and their relationships
  • Involves the study of algebraic expressions, equations, and functions

Key Concepts

  • Variables: Letters or symbols that represent unknown values or quantities
  • Constants: Numbers that do not change value
  • Algebraic Expressions: Combinations of variables, constants, and mathematical operations
  • Equations: Statements that express the equality of two algebraic expressions
  • Functions: Relations between a set of inputs (domain) and a set of possible outputs (range)

Types of Algebraic Expressions

  • Monomials: Expressions with a single term (e.g. 2x, 3y)
  • Binomials: Expressions with two terms (e.g. x + 3, 2x - 4)
  • Polynomials: Expressions with multiple terms and variables (e.g. x^2 + 3x - 4, 2y^2 - 5y + 1)

Operations on Algebraic Expressions

  • Addition and Subtraction: Combining like terms
  • Multiplication: Distributive property (e.g. 2(x + 3) = 2x + 6)
  • Division: Factoring and canceling out common terms

Solving Equations

  • Linear Equations: Equations with a degree of 1 (e.g. 2x + 3 = 5)
  • Quadratic Equations: Equations with a degree of 2 (e.g. x^2 + 4x + 4 = 0)
  • Systems of Equations: Sets of equations with multiple variables

Graphing and Functions

  • Graphs: Visual representations of functions on a coordinate plane
  • Domain and Range: The set of inputs and possible outputs of a function
  • Function Operations: Composition, inverse, and identity functions
