Study Notes
Polynomials
- Polynomials are mathematical expressions involving variables and exponents. They are fundamental in algebra.
- The degree of a polynomial is the highest exponent of the variable.
- The leading coefficient is the coefficient of the term with the highest degree.
Polynomial Forms and Characteristics
- Standard form: Arranges terms in descending order of degree.
- End behavior: Describes the polynomial's behavior as x approaches positive or negative infinity.
- Polynomials can be divided using polynomial long division.
Polynomial Operations
Addition and Subtraction
- Add or subtract polynomials by combining like terms (same variables and exponents).
- Subtract by distributing the negative sign to all terms in the second polynomial before combining like terms.
Multiplication
- Multiply polynomials using the distributive property.
- The FOIL method is a mnemonic for multiplying two binomials (First, Outer, Inner, Last).
- The product rule for exponents applies when multiplying terms with the same variable.
Operations with Multiple Variables
- Apply the same rules (addition, subtraction, multiplication) to polynomials with more than one variable.
- Combining like terms is crucial, focusing on matching both variables and exponents.
- The product rule applies when multiplying terms containing multiple variables.
Simplification of Complex Polynomials
- Simplify complex expressions by breaking them down into smaller parts and applying addition, subtraction, and multiplication.
