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...

In this video, we’ll explore a real-world exponential growth function that models the changing value of a rare painting purchased by an art museum. 🖼️

We’re solving a problem that involves a cube root inside parentheses that’s...

In this video, we examine two quadratics word problems. In the first, we do a problem involving the radius of a sprinkler in a square yard. In the second problem (2:40), we find two consecutive odd numbers that have a particular product.

In this video, we do two quadratics word problems. The first involves two square and their areas. The second involves a right triangle with polynomial side lengths.

In this video, we learn how to add, subtract, multiply, and divide complex numbers. In the dividing portion of this video (7:05), we look at how to use the complex conjugate to rewrite quotients.

In this video we learn how to solve systems of equations with elimination / combination.

Watch this video for basic definitions and applications of that Algebra ideas of domain and range.

This video explains how to use the quadratic formula to solve quadratic equations

In this video, we discuss how to simplify expressions with negative and zero exponents.

In this video you will learn how to solve equations with variables on both sides, such as 3x + 3 = x + 7

In this video, you will learn how to solve equations that have fractions by eliminating the fractions first. You will accomplish this by multiplying each side of the equation by the denominator of the fraction you are trying to eliminate

Factoring Polynomials Using the Box Method with GCF: Step-by-Step Example and Explanation.

In this video, we discuss how to factor polynomials by grouping when you start with a trinomial that has a GCF.

See how the definitions of domain and range apply to real-world situations.

In this video, we look at how to write an explicit rule for an arithmetic sequence. An arithmetic sequence is a sequence that increases by a common difference (meaning you add or subtract to get to the next term).

This video practices solving systems of equations by substitution and elimination.

In this video, we derive the rule for writing geometric sequences using the "n-1" notation.

Welcome to our comprehensive series of Advanced High School Mathematics Tutorials! This series is perfect for students, teachers, and anyone looking to deepen their understanding of higher-level mathematics. Each video breaks down...

In this math video we will learn two ways to simplify a radical expression. We will first understand that an exponent of 2 means to multiply the base by itself. We will learn to multiply radicals with the same index, you multiply the...

In this math video we will learn how to calculate exponential growth to solve a real world problem. Each variable of the exponential growth equation y=a*b^x will be explained. We will identify the information provided in the real world...

In this math video we will learn about subtracting linear expressions two ways. First we will review subtracting a polynomial expression using the horizontal method. We will identify like terms and subtract one from the other. We will...

In this math video we will find the error in student work solving a linear equation. We will clear parentheses by using the distributive property. Since there are variables on both side of the equation, we will use inverse operations and...

In this math video we will learn how to use exponent rules to simplify an expression. A mini focused lesson will be provided to review and learn about the Power of a Power Property. We will apply this property to an expression to...
