the expression (2a-3b) (6ab+4a²+9b²) is equal to
a)(8a³-27b³-6a²b+18ab²)
b)2a³-3b³)
c)8a³+27b³)
d)8a³-27b³)

Answer:

Answer will be the option (B)

Step-by-step explanation:

(2a-3b) (4a²+6ab+9b²)

(2a-3b) ((2a)²+6ab+(3b)²)

There is an identity a³-b³= (a-b) (a²+ab+b²)

so the answers will be (2a)³-(3b)³
