Completing the square is another way of solving quadratics (as well as by factorising and by using the quadratic formula). Completing the square will always work, whatever the quadratic (whereas factorising does not always work). Completing the square also helps us when sketching the graph, as it

In this video we discover what the difference of two squares means and how to factorise these ‘special’ quadratics. Click here to see more videos: https://alugha.com/FuseSchool VISIT us at www.fuseschool.org, where all of our videos are carefully organised into topics and specific orders, and to s
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

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

Rationalising the denominator is when we move a root from the bottom - the denominator - to the top (the n
