Practice_dividing_polynomials_with_remainders

After learning about the different methods in which we can find the quotient and the remainder of two polynomials, gain some practice with actually performing polynomial division yourself.

Introduction_to_factorization

Learn what factorization is all about, and warm-up by factoring some monomials.

Understanding_the_binomial_theorem

Now that you know how to use the binomial theorem in order to expand powers of binomial expressions, let's gain further insight into why this actually works!

Multiplying_monomials

As an intro to more elaborate polynomial multiplication, learn how to multiply monomials (which are polynomials with a single term). For example, multiply 2x³ and 5x⁷.

Factoring_quadratics_1

Learn how to factor quadratic expressions with a leading coefficient of 1. For example, factor x²+3x+2 as (x+1)(x+2).

Factoring_quadratics_Difference_of_squares

Learn how to factor quadratics that have the "difference of squares" form. For example, write x²-16 as (x+4)(x-4). Learn how to identify this form in more elaborate expressions. For example, write 4x²-49 as (2x+7)(2x-7).

Factoring_quadratics_Perfect_squares

Learn how to factor quadratics that have the "perfect square" form. For example, write x²+6x+9 as (x+3)². Learn how to identify these forms in more elaborate expressions. For example, write 4x²+28x+49 as (2x+7)².

Finding_zeros_of_polynomials

Use all the knowledge you have about polynomials to find their zeros (which are the input values that make the polynomial equal to zero).

Graphs_of_polynomials

Combine your knowledge about the zeros and the end behavior of a polynomial in order to sketch its graph.

Fundamental_Theorem_of_Algebra

You may already have noticed that quadratic equations always have a solution when including complex number solutions. It turns out this is true for any polynomial equation, of any degree! Learn about this and more, right here.

Common_monomial_factors

Learn about common monomial factors and how to find the greatest common factor of two monomials. For example, find the greatest common factor of 6x^2y and 9xy^2 (answer: 3xy).

Multiplying_binomials

Learn how to multiply two binomials together. For example, (3x - 7) * (10x + 2).

The polynomial remainder theorem allows us to easily determine whether a linear expression is a factor of a given polynomial. Learn exactly what the theorem means, practice using it, and learn about its proof.

Quadratic_equations_with_complex_numbers

Remember all these quadratic equations with "no real solution"? Well, it turns out those equations do have a solution, it's just a complex number! Solve a bunch of those here.

Intro_to_polynomials

Learn about polynomial expressions: What are they? How are they constructed? What can we do with them?

Special_products_of_binomials

Learn about the special types of products of binomials: perfect squares and the difference of two squares. These will be very helpful once you tackle more advanced expressions in Algebra.

Factoring_polynomials_by_taking_common_factors

Learn how to take a common monomial factor out of a polynomial expression. For example, write 2x^3+6x^2+8x as (2x)(x^2+3x+4).

Multiplying_monomials_by_polynomials

Learn how to multiply a polynomial expression by a monomial expression. Monomials are just polynomials with a single term!

You may already be familiar with types of symmetries of geometrical shapes. Learn how functions can be symmetrical too!

Factoring_polynomials_with_quadratic_forms

Learn how to factor quadratic polynomials of the form ax^2+bx+c as the product of two linear binomials. For example, write x^2+3x-10 as (x+5)(x-2). Learn how to identify these forms in more elaborate polynomials that aren't necessarily quadratic. For example, write x^4-4x^2-12 as (x^2+2)(x^2-6).

Zeros_of_polynomials_and_their_graphs

Learn how to use the zeros of polynomials to draw a pretty good sketch of their graphs.

See a few examples of how we can represent real-world situations with polynomials.

Factoring_polynomials_with_special_product_forms

Factor polynomials of various degrees using factorization methods that are based on the special product forms "difference of squares" and "perfect squares." For example, factor 25x⁴-30x²+9 as (5x²-3)².
