Understanding Polynomials
Identify and classify polynomials in Grade 10 algebra by degree and number of terms, understand standard form, and evaluate polynomials by substituting values for the variable.
Key Concepts
New Concept A polynomial is a monomial or sum of monomials. The terms of a polynomial are its monomials.

Common Questions
How do you identify the degree and leading coefficient of a polynomial?
The degree is the highest exponent of the variable. The leading coefficient is the coefficient of the term with the highest degree. In 4x³-2x+1, degree=3, leading coefficient=4.
How do you evaluate a polynomial like P(x)=x³-2x+5 at x=3?
Substitute x=3: P(3) = 3³-2(3)+5 = 27-6+5 = 26.
What is the difference between a monomial, binomial, and trinomial?
A monomial has one term (e.g., 5x²). A binomial has two terms (e.g., x+3). A trinomial has three terms (e.g., x²+2x+1). All are types of polynomials.
