Factoring Polynomials with Leading Coefficient of 1

Front

What is a polynomial?

Back

A polynomial is a mathematical expression consisting of variables (also called indeterminates) raised to whole number powers and coefficients. For example, 2x^2 + 3x + 1 is a polynomial.

What does it mean to factor a polynomial?

Back

Factoring a polynomial means expressing it as a product of its factors, which are polynomials of lower degrees. For example, factoring x^2 - 5x + 6 gives (x - 2)(x - 3).

What is the leading coefficient of a polynomial?

Back

The leading coefficient is the coefficient of the term with the highest degree in a polynomial. For example, in the polynomial 3x^2 + 2x + 1, the leading coefficient is 3.

Front

What is the standard form of a polynomial?

Back

The standard form of a polynomial is written in descending order of the degree of its terms. For example, 4x^3 + 2x^2 - x + 5 is in standard form.

What is the difference between a monomial, binomial, and trinomial?

Back

A monomial has one term (e.g., 3x), a binomial has two terms (e.g., x + 2), and a trinomial has three terms (e.g., x^2 + 3x + 2).

What is the zero-product property?

Back

The zero-product property states that if the product of two factors is zero, then at least one of the factors must be zero. For example, if (x - 2)(x + 3) = 0, then x - 2 = 0 or x + 3 = 0.

How do you factor a quadratic polynomial of the form x^2 + bx + c?

Back

To factor a quadratic polynomial of the form x^2 + bx + c, find two numbers that multiply to c and add to b. For example, for x^2 + 5x + 6, the numbers are 2 and 3, so it factors to (x + 2)(x + 3).

Front

What is the significance of the constant term in a polynomial?

Back

The constant term in a polynomial is the term without a variable. It affects the y-intercept of the graph of the polynomial function.

Front

What is the relationship between the roots of a polynomial and its factors?

Back

The roots of a polynomial are the values of the variable that make the polynomial equal to zero. Each root corresponds to a factor of the polynomial.

How can you check if your factorization is correct?

Back

You can check if your factorization is correct by multiplying the factors back together to see if you obtain the original polynomial.
