17 Factorisation (EMAG) Factorisation is the opposite process of expanding brackets For example, expanding brackets would require \ (2 (x 1)\) to be written as \ (2x 2\) Factorisation would be to start with \ (2x 2\) and end up with \ (2 (x 1)\) The two expressions \ (2 (x 1)\) and \ (2x2\) are equivalent;Example 4 Factor 49 x 2 − 100 y 2 Solution Here we have a binomial with two variables and recognize that it is a difference of squares Therefore, a = 7 x and b = 10 y Substitute into the formula for difference of squares CHAPTER 7 FACTORISING ALGEBRAIC EXPRESSIONS 177 Factorise the following completely a 5x 15 y b −3m − m2 c 6xy − 2 x d 15 p − q e 15 pq − q f 12 st 2 15 st g −18 xy − 6 x h at − at 2 i 7x2y xy j a2 ab Factorise each of the following a a2 ab 3 a b xy − 3 x2 2 x c 12 st − 4 t3 8 t d 36 − 12 ab 18 b e 3ab − 9 a2b 12 ab 2 a2b2 f 4m − 8 n −

 In this case, our perfect squares are x2 and one hundred, so this can be factored out as (x 10)(x 10)Get stepbystep solutions from expert tutors as fast as 1530 minutes Your first 5 questions are on us! This is known as a difference of squares It can be factored as x^2 y^2 = (xy)(xy) Notice that when you multiply (xy) by (xy) then the terms in xy cancel out, leaving x^2y^2 (xy)(xy) = x^2xyyxy^2 = x^2xyxyy^2 = x^2y^2 In general, if you spot something in the form a^2b^2 then it can be factored as (ab)(ab) For example 9x^216y^2 = (3x)^2(4y)^2
