A surd is a square root which cannot be reduced to a whole number. Surds are irrational; they are decimals that never end and never repeat, so cannot be written as fractions. Leaving a number in it's surd form is easier and more accurate than writing and rounding the decimal places. We see surds

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
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

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
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
