Polynomials
Polynomials are expressions consisting of variables and coefficients. They are used to represent mathematical relationships and model real-world phenomena. Key concepts and formulas related to polynomials include:
- Degree of a polynomial
- Leading coefficient
- Constant term
- Standard form of a polynomial
- Operations on polynomials (addition, subtraction, multiplication, division)
Polynomials are used in various applications, such as modeling growth patterns, predicting future trends, and solving complex equations. For example, a quadratic polynomial can be used to model the trajectory of a projectile, while a cubic polynomial can be used to approximate the volume of an irregularly shaped object.
Rational Expressions, Unit 1 test algebra 2 answers
Rational expressions are fractions involving polynomials. They are used to represent ratios of quantities and model real-world situations. Key concepts and formulas related to rational expressions include:
- Simplifying rational expressions
- Multiplying and dividing rational expressions
- Adding and subtracting rational expressions with like denominators
- Solving rational equations
Rational expressions are used in various applications, such as calculating rates, proportions, and probabilities. For example, a rational expression can be used to determine the average speed of a car over a given distance, or to calculate the probability of an event occurring.
Linear Equations and Inequalities
Linear equations and inequalities represent relationships between variables that can be graphed as straight lines. Key concepts and formulas related to linear equations and inequalities include:
- Slope-intercept form of a linear equation
- Point-slope form of a linear equation
- Solving linear equations and inequalities
- Graphing linear equations and inequalities
Linear equations and inequalities are used in various applications, such as modeling relationships between variables, predicting outcomes, and making decisions. For example, a linear equation can be used to model the relationship between the temperature and the volume of a gas, or to determine the break-even point for a business.
Systems of Linear Equations
Systems of linear equations consist of two or more linear equations that are solved simultaneously. Key concepts and formulas related to systems of linear equations include:
