Study Notes
Algebraic Expressions
- Composed of constants (numbers) and variables (letter notations).
- Essential for forming equations and functions in mathematics.
Constants
- Defined as numerical values that do not change.
- Fundamental components in algebraic expressions.
Variables
- Represented by letters and can take on different values.
- Used to express general formulas and equations.
Simplification
- Process of combining numbers and like terms in an expression.
- Aims to make expressions easier to work with or understand.
Evaluating the Expression
- Involves simplifying the expression to result in a numerical value.
- Critical step in solving equations.
Order of Operations
- Follow the acronym EMDAS to simplify expressions:
- E (Exponentiation)
- M (Multiplication)
- D (Division)
- A (Addition)
- S (Subtraction)
Polynomial Expressions
- Made up of different powers of variables multiplied by constants.
- Terms are connected by addition or subtraction operators.
Terms
- Individual parts of a polynomial that are separated by "+" or "-" signs.
- Each term can contain coefficients and variables.
Coefficient of the Term
- Refers to the numerical factor in front of a variable in a term.
- Helps determine the weight or importance of a term in polynomials.
Degree of a Term
- Calculated by summing the powers of all variables present in that term.
- Indicates the complexity and classification of polynomial terms.
Rule #1 for Terms
- The degree of any non-zero constant term is defined as zero.
- Example: The term "7" has a degree of zero.
Rule #2 for Terms
- The degree of the constant term "0" is not defined.
- Important to acknowledge in polynomial equations.
Degree of the Polynomial
- Represents the highest degree of any term within the polynomial.
- Crucial for understanding the polynomial's behavior and graphing.
