Question

expand each of the following using suitable identies for
(2a-3b)​

Answer 1

*****************************************

We know the algebraic identity,

( x - y )³ = x³ - 3x²y + 3xy² - y³

*******************************************

Now ,

( 2a - 3b )³

= (2a)³-3*(2a)²*3b+3*2a*(3b)²-(3b)³

= 8a³ - 3*4a²*3b+6a*9b²-27b³

= 8a³ - 36a²b + 54ab² - 27b³
