    Study Notes

    Polynomials and Algebraic Expressions

    • Polynomials: Consist of more than two algebraic terms.
    • Monomial: Can be a single number, a variable, or a combination of both.
    • Binomial: Defined as a polynomial formed from exactly two terms.
    • Trinomial: A polynomial containing three distinct terms.

    Algebraic Concepts

    • Algebraic Expression: Made up of numbers, variables, and at least one operation like addition or multiplication.
    • Like Terms: Terms that share identical variable factors raised to the same power, allowing them to be combined.
    • Perfect Square: A number that results from squaring an integer.

    Mathematical Statements

    • Equation: Represents a mathematical assertion that two expressions hold equal value.
    • Leading Coefficient: Identifies the coefficient in the term with the highest degree in a polynomial.

    Polynomial Characteristics

    • Standard Form: Polynomials organized in descending order by degree.
    • Variable: A symbol that signifies a changing quantity.
    • Expression: Refers to a mathematical statement that includes numbers, operations, and/or variables.

    Properties and Operations

    • Inverse Operations: Refer to operations that cancel each other out (e.g., addition and subtraction).
    • Equivalent: Terms or expressions that hold equal value.
    • Coefficient: The numerical factor that precedes a variable in an expression.

    Structural Elements of Expressions

    • Terms: Can be standalone numbers, variables, or a mix of both.
    • Constant Term: A specific term devoid of a variable component.
    • Combining Like Terms: The process of simplifying expressions by merging terms with the same variables and constants.

    Algebraic Techniques

    • Distributive Property: A critical algebraic principle stating a(b + c) = ab + ac, used for expanding expressions.
    • Simplest Form: A state where an algebraic expression has no like terms and no parentheses remaining.
    • Factoring: The method of rewriting an expression as a product of its factors.

    Factors in Mathematics

    • Greatest Common Factor (GCF): The largest factor shared by two or more numbers.
    • Variable Term: Specifically refers to any term in an expression that includes a variable.
