Introduction
•Algebra requires you to manipulatealgebraic expressions •We have covered simplifying expressions and solving equations •Now we look at manipulating expressions through expanding and factorising •First, we recap some mathematical ideas that will assist factorisation •Second, we revise the distributive law •Third, you will learn how to expand two or more sets of brackets RecapMultiples
A multipleis a number that can be
divided into a given number exactly -For example: multiples of 5 are 5, 10, 15,20, 25...
Recap •Common multiples and the LCM •A common multiple is a multiple in which two or more numbers have in common -For example: 3 and 5 have multiples in common 15, 30, 45... •The lowest common multiple LCM is the lowest multiple that two numbers have in common -For example: 15 is the LCM of 3 and 5 153 5
Recap •Factor-a whole number that can be multiplied a certain number of times to reach a given number -3 is factor of 15 and 15 is a multiple of 3 -The other factors are 1and 15 -4 is a factor of 16 and 16 is a multiple of four, other factors -1, 2, 4, 8, 16 Recap •A common factor is a common factor that two or more numbers have in common -3 is a common factor of 12 and 15 -5 is a common factor of 15 and 25 -6 is a common factor of 12 and 18 •The highest common factor -HCF -What is the HCF of 20 and 18? -the factors of 20 (1, 2, 4, 5, 10, 20) and 18 (1, 2,3, 6, 9, 18)
-the common factors are 1 and 2 and -the HCF is 2 Recap •We could say that a number is a factor of given number if it is a multiple of that number •For example, -9 is a factor of 27 and 27 is a multiple of 9 -7 is a factor of 35 and 35 is a multiple of 7 -14 is a factor of 154 and 154 is a multiple of 14YouTube clip
multiples Recap •Proper factors -All the factors apart from the number itself -18 (1, 2, 3, 6, 9, 18) 1, 2, 3, 6, 9 are proper factors of 18 •Prime number -Any whole number greater than zero that has exactly two factors -itself and one 2, 3, 5, 7, 11,13, 17, 19...
•Composite number -Any whole number that has more than two factors -4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20...Factor tree
