Study Notes
Polynomials Overview
- Polynomials are algebraic expressions consisting of variables, coefficients, and non-negative integer exponents.
- A polynomial must not include divisions by variables or roots of variables.
Identifying Polynomials
- Examples of valid polynomials include:
- x^3y - 3x^2 + 6x
- -1/3x^3 - 1/2x^2 + 1/4
- Non-examples include:
- 2x^3 - 1/x (division by x)
- y^2 + 5y - sqrt3 (involves a square root)
Polynomial Types and Representation
- A polynomial can be classified as:
- Trinomial: has three terms, e.g., -2x^2 - x + 2.
- Binomial: has two terms, e.g., 6y^2 - y.
- The arrangement in standard form typically has terms ordered by descending degree.
Polynomial Degree
- The degree of a polynomial is determined by the highest exponent in the expression.
- A polynomial with a degree of 3 can be represented as:
- 2y^3 + 5y^2 - 5y.
Simplification and Standard Form
- Combining like terms effectively simplifies a polynomial.
- An example of simplification: for -5x^3y^3 + 8x^4y^2 - xy^5 - 2x^2y^4 + 8x^6 + 3x^2y^4 - 6xy^5, the standard form is:
- 8x^6 + 8x^4y^2 - 5x^3y^3 + x^2y^4 - 7xy^5.
Analysis of Polynomial Expressions
- Different arrangements of a polynomial can still qualify as standard form depending on the variable order.
- Both forms by Marcus and Ariel are acceptable based on their order of variables (x and y).
Creating Polynomials
- To create polynomials with a specific degree (e.g., degree of 5), include appropriate terms such as:
- 8.4x^4y^2 or 5x^4y.
Conclusion on Polynomial Forms
- Understanding the classification, degrees, simplification, and standard forms is crucial for working with polynomials in algebra.
