In algebra expanding brackets means to remove the brackets. In this video we’ll look at how to expand single brackets 2(3x - 4), and in another video we’ll discover how to expand double brackets (x - 5)(x + 3). Click here to see more videos: https://alugha.com/FuseSchool VISIT us at www.fuseschool
In this video we’re going to look at how to expand double brackets. Once we know how to expand double brackets, we’ll also be able to expand triple brackets and so on, so we’ll have a look at a triple bracket example towards the end of this video. VISIT us at www.fuseschool.org, where all of our vi
It is know as factorising in England and factoring in America. They mean to put an expression into brackets. We say it has been factorised. Numbers have factors, the factors of 6 are 1, 2, 3 and 6. Expressions can also have factors like this: 6x - 12 = 3(2x - 4). Factorising is the process of findin
In this video we’re going to have a look at how to expand squared brackets. You should already know how to expand double brackets by multiplying each term in the first bracket, by each term in the second bracket and then simplifying. EXAMPLE: (x - 4)(x + 3) = x^2 - 4x + 3x - 12 = x^2 - x - 12. For

In this video we’re going to discover how to factorise quadratics that don’t have 1 as the coefficient of the x-squared term. These are called non-monic quadratics. VISIT us at www.fuseschool.org, where all of our videos are carefully organised into topics and specific orders, and to see what else
Power laws simply explained - power, base, exponents - same base - analysis. A power consists of a base and an exponent, the exponent is often written as a superscript. The power laws help you calculate. You either keep the base or the exponent. There is also a case where a power is put in brackets.

In this video we are going to look at how to change the subject of a formula, when the subject appears twice. We have already looked at how to change the subject in another video, so you may want to watch that first. We always use opposites: adding and subtracting, multiplying and dividing, squaring

This video shows the assembly and mounting of the wireless tilting sensor RF RW SW868 / 915-NET. Thanks to a universal bracket to suit roller conveyors from different leading manufacturers, the sensor can be mounted quickly and easily, as well as integrated in existing rack systems.
In algebra, we replace a letter with numbers in the process known as substitution. Given the formula A = 1/2bh, if the base is 5cm and the height is 10cm, then the area is ½ X 5 X 10 because we have replaced the b with 5 and the h with 10. You just need to be be careful with negative numbers: it is
