We know the corollary if a b c = 0 then a 3 b 3 c 3 = 3 a b c Using the above identity taking a = x − y , b = y − z and c = z − x , we have a b c = x − y y − z z − x = 0 then the

To expand this, we're going to use binomial expansion So let's look at Pascal's triangle 1 1 1 1 2 1 1 3 3 1 Looking at the row that starts with 1,3, etc, we can see that this row has the numbers 1, 3, 3, and 1 These numbers will be the coefficients of our expansion So to expand , Ex 25, 4 Expand each of the following, using suitable identities (x 2y 4z)2 (x 2y 4z)2 Using (a b c)2 = a2 b2 c2 2ab 2bc 2ac Where a = x , bExpand the following ` (i) (3a2b)^ (3) (ii) ( (1)/ (x) (y)/ (3))^ (3)` (iii) ` (4 (1)/ (3x))^ (2)` Watch later Share Copy link Info Shopping Tap to unmute If playback doesn't begin
