Learn how to rewrite a quadratic expression so that all of the variable terms are contained in a perfect square. We explore this process using area blocks and show how to complete the square in an expression. We also emphasizes the...

There has been a lot of talk in Britain about the need for a new centrist political party. Political commentator Janan Ganesh talks to FT editor Lionel Barber about whether this is something that could happen.

In this video, the teacher explains why (A+B)^2 is not equal to A^2 + B^2 and demonstrates how to prove the correct expansion using an area model. By visually representing the square of a binomial, the teacher shows that it consists of...

This lesson begins with a review of equivalent fractions and the concept of common denominators. It then demonstrates how to deconstruct mixed numbers into fractional parts and multiply to form equivalent fractions. Finally, the video...

👉Learn how to solve a system (of equations) by elimination. A system of equations is a set of equations which are collectively satisfied by one solution of the variables. The elimination method of solving a system of equations involves...

👉 Learn how to add and subtract mixed numbers. Mixed numbers are numbers with two parts: the whole number part and the fraction part. Mixed numbers are ways to represent improper fractions using proper fractions.To add or subtract mixed...

The Black Death changed the world. As the most profound epidemic in human history, the plague claimed the lives of millions, with nearly half of Europe's population perishing from the disease. Some feared they were living through the...

In this video, you will learn how to rewrite quadratic functions in standard form to reveal the vertex. By completing the square, you can manipulate the function into vertex form, which allows for easy identification of the vertex.

It cost the equivalent of billions of dollars in today’s money, and left the US government crippled with debt. But how, exactly, did America pay for the Civil War?

In this lesson, students will learn how to create equivalent fractions by multiplying both the numerator and denominator of a fraction by the same number. They will explore this concept through visual representations on number lines.

Once a system of linear equations has been converted to augmented matrix form, that matrix can then be transformed using elementary row operations into a matrix which represents a simpler system of equations with the same solutions as...

In this video, you will learn how to find the multiplicative inverse of a number and use it to write equivalent expressions. The multiplicative inverse, also known as the reciprocal, is the number that, when multiplied by the original...

👉 Learn how to solve one step linear equations. By one step we mean equations that take one step to solve. The one step is the inverse operation needed to isolate the variable such as addition, subtraction, division and multiplication...

This week on Blockchain Central: we are going to take a look at the controversial Tether - a cryptocurrency that is backed by the US dollar. We'll describe it, discuss its goal, and learn about the Proof of Reserves mechanism....
