Study Notes
Equations
- Definition: An equation is a statement that says two mathematical expressions are equal.
-
Types of Equations:
- Linear Equations: Equations in which the highest power of the variable(s) is 1. (e.g., 2x + 3 = 5)
- Quadratic Equations: Equations in which the highest power of the variable(s) is 2. (e.g., x^2 + 4x + 4 = 0)
- Polynomial Equations: Equations involving polynomials.
-
Equation Operations:
- Addition and Subtraction: Adding or subtracting the same value to both sides of an equation.
- Multiplication and Division: Multiplying or dividing both sides of an equation by a non-zero value.
Polynomials
- Definition: A polynomial is an expression consisting of variables and coefficients combined using only addition, subtraction, and multiplication.
-
Properties of Polynomials:
- Degree: The highest power of the variable(s) in a polynomial.
- Terms: Individual parts of a polynomial separated by addition or subtraction.
- Coefficients: Numbers multiplied by variables in a polynomial.
-
Operations with Polynomials:
- Addition and Subtraction: Combining like terms.
- Multiplication: Distributing each term of one polynomial to each term of the other polynomial.
-
Factoring Polynomials:
- Greatest Common Factor (GCF): Factoring out the largest common factor from each term.
- Difference of Squares: Factoring quadratic expressions in the form of a^2 - b^2 = (a + b)(a - b).
