Polynomial Fundamentals
A polynomial is an expression built from variables, coefficients, and non-negative integer exponents using addition, subtraction, and multiplication. The standard form looks like , where the constants ( to ) are called coefficients.
The degree of a polynomial is the highest power of the variable. For example, in , the degree is 2. Each part separated by addition or subtraction is called a term, and the numerical factor in each term is its coefficient. The coefficient of the highest-degree term (like the 3 in ) is the leading coefficient.
When adding or subtracting polynomials, you simply combine like terms. For instance, gives you . This works because terms with the same variables and exponents can be grouped together.
Quick Tip: When working with polynomials, always arrange terms in descending order of degree (highest power first). This makes operations easier and helps avoid mistakes!

Polynomial Operations and Theorems
Multiplying polynomials involves distributing each term from one polynomial to every term in the other. For example, . You'll frequently use special product formulas like and to multiply efficiently.
Factoring is the reverse of multiplication—expressing a polynomial as a product. For instance, factors as . This skill is crucial for solving polynomial equations and simplifying expressions.
Polynomials have several important theoretical properties. The Remainder Theorem states that when dividing a polynomial by a linear factor , the remainder equals . The Factor Theorem builds on this: if , then is a factor of .
Remember: The zeros or roots of a polynomial are the values that make the polynomial equal to zero. Finding these values is often your main goal when solving polynomial equations!
