Perform operations of addition, subtraction, and multiplication on polynomials, including combining like terms and applying the distributive property.
Definitive Answer: Perform operations of addition, subtraction, and multiplication on polynomials, including combining like terms and applying the distributive property.
In mathematics, a **polynomial** is an algebraic expression composed of variables, constants, and exponents, combined using addition, subtraction, and multiplication. Each component of a polynomial separated by a plus or minus sign is called a **term**. For example, in the polynomial `5x^2 - 3x + 7`, the terms are `5x^2`, `-3x`, and `7`. The numerical part of a term is its **coefficient**. This structure is fundamental in various fields, such as architecture, where a polynomial might model the area of a floor plan with different types of rooms (`x^2` for large rooms, `x` for hallways, and constants for storage space). The primary principle governing the addition and subtraction of polynomials is the combination of **like terms**. Like terms are defined as terms that possess the identical variable raised to the identical power. The process is analogous to sorting and counting objects of the same type. To add polynomials, one simply identifies and combines the coefficients of all like terms. For subtraction, a critical preliminary step is required: the distributive property must be applied to the negative sign. This means inverting the sign of every term within the polynomial being subtracted. Following this distribution, the operation proceeds as a standard addition of like terms.
| Term | Definition |
|---|---|
| Polynomial | An expression consisting of variables and coefficients, involving only the operations of addition, subtraction, multiplication, and non-negative integer exponents. |
| Term | A single mathematical expression which may be a number, a variable, or numbers and variables multiplied together. In a polynomial, terms are separated by `+` or `-` signs. |
| Coefficient | The numerical factor of a term that contains a variable. In the term `5x^2`, the coefficient is `5`. |
| Like Terms | Terms that have the same variable(s) raised to the same power(s). Only the coefficients of like terms can be combined using addition or subtraction. |
