Question

find the product using appropriate identity :- (2a + 3b) × (4a^2 -6ab +9b^2)​

Answer 1

(2a + 3b) × (4a² - 6ab + 9b²)

Using property :- (a+b) (a² - 2ab + b²) = a³ + b³

= (2a)³ + (3b)³

= 8a³ + (3b)³

= 8a³ + 27b³

$\boxed{Ans : 8a³+27b³}$

Answer 2

Step-by-step explanation:

(2a)³ + (3b)³

= 8a³ + (3b)³

= 8a³ + 27b³
