I can't answer
why
(2a + 3b) ³ - ( 2a + 3b) ³ =0. As , = 8a³ + 27 b³ + 18ab( 2a+3b ) - [ 8a³ + 27b³ + 18ab( 2a+ 3b) ] = 8a³ + 27 b³ + 36a²b + 52ab² ...

Answer:
option b) is your answer
Step-by-step explanation:
it's simply want you to find the identities hided in the equation
(2a + 3b)^3 - 18ab (2a+ 3b)
now u can see that they are forming an identity solution
a^3 + b ^3
= (a+ b )^3 -3ab ( a+b )
does this identity seems similar to your question now compare it and then u can find your answer
