During this shorts math video I will be using the area model to factor a quadratic expression. We will use a rectangle as a graphic organizer to support our success factoring a quadratic expression. We will draw a rectangle and divide...

In this short math video we will learn how to use the Zero Product Property to find the zeroes of a quadratic function in factored form. We will understand that the Zero Product Property states that any quantity a multiplied by a...

In this Algebra 1 lesson, we will identify the correct vertex form of the given graph of a quadratic function. We dive into Common Core Standard HS.F-BF.3 as we explore how transformations affect functions — specifically...

In this Algebra 1 video, students quickly analyze a table of values and four possible functions to determine which function best represents the data. We begin by noticing the domain increases by 1 each time, but the range does not have a...

A video entitled "Graph Key Quadratic Features" that covers the process of graphing a quadratic function using its intercepts and vertex.

In this video, we do quadratics word problems that can be solved using vertex form of a quadratic.

This video will review how to interpret the different features of linear, quadratic, and exponential functions.

A polynomial is a sum of one or more terms called monomials. If we think of each monomial as a separate function, then a polynomial function can be thought of as a sum of these monomial functions. In previous lectures we have studied...

In this short math video we will be presented with 5 equations and asked to identify the equations that are linear functions. We will understand that a linear function must be able to be written in the form y=mx+b. We will also...

In this video, the teacher explains how to solve a system of equations that includes both a quadratic and a linear equation. The method used is substitution, where one equation is substituted into the other to eliminate one variable. The...

This video discusses the limitations of using zeros to graph a quadratic function and introduces the concept of functions with no zeros or real roots. It explains that if a quadratic function has no real number values that make it equal...

This video explains how to find the zeros of first and second-degree polynomial functions by setting the function equal to zero and solving for x. It also discusses the concept of linear functions and their x-intercepts, as well as the...

In this video, we explore the concept of domain restrictions in quadratic functions by analyzing real-life scenarios involving linear and quadratic functions. We learn about function notation, linear functions with constant rate of...

Before the method of completing the square was developed, only very limited types of quadratic equations could be solved. This method eliminated those limitations, allowing the solutions of any quadratic equation to be found. As...

In this video, you will learn how to use the graph of a quadratic function to find the best price for selling stuffed animals. By finding the zeros of the function and understanding the relationship between price and sales, you can...

In this video, the teacher explains how to find the zeros of a quadratic function by factoring a trinomial. They explain the zero product property and the importance of factoring completely. They then demonstrate how to apply these...

In this video, the teacher explains how to factor a quadratic function to find its zeros. They demonstrate the process using examples and highlight common mistakes to avoid.

In this video, the teacher explains how to write the equation of a parabola using different methods. They also demonstrate how to solve systems of equations and find the vertex of a parabola. The video concludes by applying these...

In this lesson, we explore the different forms of quadratic functions and how they provide useful information about the function. Specifically, we focus on the factored form of a quadratic function, which allows us to easily identify the...

In this lesson, students will learn how to identify the zeros of a quadratic function that fits the perfect square pattern by factoring. They will understand that the zeros of a function are the input values that make the function equal...

In this video, the teacher explains how to factor a quadratic function to reveal its zeros. They demonstrate the process step by step and provide examples for better understanding.
