New ReviewIn this video I am going to work through completing the square, the basics of what you need to know

New ReviewIn this video I am going to go over the three rules of the quadratic formula that you need to know. It's not just about plug and chug. There is so much more to it.

New ReviewIn this video we are going to compare the difference of rationalizing the denominator when you have one radical vs a binomial with one radical.

New ReviewIn this video we are going to take a look solving radical equations one that is a simple one and one that is more advanced

New ReviewThis video explains how to solve three different square root equations (0:00). Brian McLogan demonstrates how the placement of the radical impacts the steps to solve the equation and the final solution (0:12). He covers isolating the...

New ReviewThis video explains how to solve a square root equation using the "peel the onion" strategy (0:00). The method involves isolating the function by undoing operations from the outermost layer inward, starting with addition/subtraction,...

New ReviewLets go ahead and multiply two radical expressions and then simplify the result.

It's a math teacher's dream!

In this shorts video we will factor a quadratic to solve a problem. We will draw and label a picture to represent the problem. We will use a square to model perfect squares and support factoring a quadratic. This quadratic is a...

In this shorts video we will find the area of a Valentine's Day Heart. We will be presented with a composite figure, a heart. A composite figure is a figure composed of two or more two-dimensional figures. The heart is formed by a...

In this shorts video we will answer a standardized math test question by using The Pythagorean Theorem in the Real World. We will be presented with a problem to find the diagonal distance from the top of a flagpole to a point on the...

In this shorts math video we will find the side of a square using area. We are given the area of a square and asked to find the side length of the square. We will review and use the formula A=s^2, (A equals s squared.) We will rewrite...

In this Algebra 1 math video, we’ll use the laws of exponents to evaluate a radical expression — perfectly aligned with Standard HS.N-RN.A.2.

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

With 2.7 million inhabitants, Rome is Italy's most populated city. It is also the nation's capital, and all international embassies are located here. Rome also contains Vatican City, the headquarters of the Roman Catholic Church. Home to...

In this video, you will learn to use the one-way ANOVA, where there is only one dependent factor.

This is the solution to the practice exercise to estimate how well a regression works using the root mean square error method.

In this lecture, you will learn another important metric to determine the quality of our regression using the root mean square error method.

This is the solution to the practice exercise on the mean square error and mean absolute error to check the accuracy of our regression.

This lesson will teach us an intuitively understandable matrix for how our regression works.

This is the solution to the practice exercise on Pearson's coefficient regression analysis.

Let’s learn shapes together! In this fun and colourful video, kids will learn shape vocabulary with talking flashcards and then play exciting interactive games like "Guess the Shape," "Find the Shape," and "Pick a Shape Surprise." This...

Learn how astrophysicists use the orbital motion of a visible star—its speed and period—to infer the mass of its invisible companion, often a black hole, in a binary system.

A neutron star spinning at 1 revolution per second is on the edge of tearing itself apart. This lesson breaks down the physics of rotational stability, showing how gravity and circular motion determine the star's minimum mass.

Learn how to calculate gravitational attraction between a point mass and a uniform rod using integration and Newton’s law of universal gravitation—essential for advanced physics students.
