Study Notes
Algebraic Expressions and Terms
- An algebraic expression involves at least one variable, numbers, and operation symbols, forming a mathematical phrase.
- A term refers to either a single number or a variable with an exponent.
- The variable denotes the letter that represents an unknown value within a term.
- The exponent is a small number next to the variable indicating the power to which the variable is raised.
Like and Unlike Terms
- Like terms are defined as terms that share the same variable and have identical exponents.
- Simplifying an expression requires combining like terms, which means you can only add or subtract terms that are alike.
Polynomials
- A polynomial consists of one or more terms combined through addition or subtraction, forming a specific type of algebraic expression.
Operations with Polynomials
- When adding polynomials, the process involves regrouping and summing like terms to form a combined expression.
- For subtracting polynomials, the first step is to change the signs of all terms within the second polynomial, followed by adding the adjusted terms to the first polynomial.
