Study Notes
Definition
- A polynomial is an expression consisting of variables and coefficients combined using only addition, subtraction, and multiplication.
- The variables are raised to non-negative integer powers.
Examples
- Simple polynomials: 2x, 3x^2, 5
- Polynomials with multiple terms: 2x + 3, x^2 - 4x + 2
Properties
- Degree: The highest power of the variable(s) in the polynomial. (e.g., 2x^2 + 3x has a degree of 2)
- Leading term: The term with the highest degree. (e.g., 2x^2 in 2x^2 + 3x)
- Leading coefficient: The coefficient of the leading term. (e.g., 2 in 2x^2)
Operations
- Addition: Polynomials can be added by combining like terms.
- Subtraction: Polynomials can be subtracted by combining like terms with opposite signs.
- Multiplication: Polynomials can be multiplied using the distributive property.
Special Types of Polynomials
- Monomial: A polynomial with only one term. (e.g., 2x)
- Binomial: A polynomial with two terms. (e.g., x + 2)
- Trinomial: A polynomial with three terms. (e.g., x^2 + 2x + 1)
Factoring Polynomials
- Factoring out the greatest common factor (GCF): Finding the GCF of all terms and dividing it out.
- Factoring quadratic expressions: Using the form x^2 + bx + c = (x + d)(x + e) to factor quadratic expressions.
Definition of Polynomials
- A polynomial consists of variables and coefficients combined using only addition, subtraction, and multiplication.
- Variables in a polynomial are raised to non-negative integer powers.
Characteristics of Polynomials
- Simple polynomials can be represented by a single term, such as 2x or 3x^2.
- Polynomials can have multiple terms, such as 2x + 3 or x^2 - 4x + 2.
Properties of Polynomials
- The degree of a polynomial is the highest power of the variable(s) in the polynomial.
- The leading term is the term with the highest degree in the polynomial.
- The leading coefficient is the coefficient of the leading term.
