A quick way to compute eigenvalues of a 2x2 matrix

What is a vector space? Even though they are initial taught in the context of arrows in space, or with vectors being lists of numbers, the idea is much more general and far-reaching.

New ReviewThis video provides a step-by-step guide on performing long division with polynomials (0:00). The presenter emphasizes the importance of arranging terms in descending order (0:19) and demonstrates the process using an example, including...

In this shorts video we will learn how to factor a trinomial to answer a standardized math test question. We will first examine our answer choices and understand that each has been factored using a value of 8. We will use the table...

In this shorts math video we will answer a standardized math test question where we learn how to multiply binomials using the area method. We will recognize the math expression to be the product of two binomials. We will set up a two...

In this shorts math video we will factor using difference of squares to answer a standardized math test question. We will begin by identifying the first and last term are both perfect squares. We will identify the pattern of difference...

In this math video we will review how to simplify a polynomial expression. We will begin by clearing the parentheses using the Distributive Property. We will review that you multiply each term inside the parentheses by the factor...

In this math video we will learn how to multiply a monomial by a binomial to simplify an algebraic expression. We will be presented with an algebraic expression which represents a monomial multiplied by a binomial (two term expression)....

Factoring is the opposite of distributing. If you can find a common factor, you can reduce an expression.

The rules of multiplication extend beyond multiplying 2 whole numbers. Here are some of the others.

In this video, we work through a few examples of polynomial long division, and we relate it to long division of constants (regular numbers).

In this video, we factor polynomials with long division. Specifically, we look at examples where there is a "missing term," and we discover how to rewrite the polynomial so that it factors nicely.

In this video, we will factor polynomials that don't initially appear to be in the form of a quadratic. We will accomplish this by rewriting them in the form of a quadratic with substitution.

In this video, we define rational expression, and find the domain of rational expressions.

In this video, we rewrite polynomials into factored form when given a zero.

This video is an introduction to the rational root theorem. First, we define the rational root theorem, and then use one example to find ALL roots of a polynomial.

In this video, we do two examples of using the rational root theorem to find all zeros of a polynomial function.

In this video, we investigate if a given binomial is a factor of a polynomial.

In this video, we define and use the conjugate zeros theorem to write a polynomial function

In this video, we use our knowledge of power functions to predict the end behavior of polynomial functions.

In this video, we define rational functions and examine how to graph simple rational functions as transformations to the reciprocal function.

The video shows how to graph a 4th‑degree polynomial using its leading term, rational root theorem, and synthetic division:
