HOPE THIS ANSWER WILL HELP YOU ☺️

Step-by-step explanation:

(2a + 3b) × (2a - 3b) × (4a² - 9b²)

identity will be used is ;

(a + b) (a - b) = a² - b²

(2a)² - (3b)² × (4a² - 9b²)

(4a² - 9b²) (4a² - 9b²)

(4a² - 9b²)²

identity will be used is ;

(a - b)² = a² - 2ab + b²

(4a² - 9b²)² = (4a²)² - 2(4a) (9b) + (9b²)²

= 16a⁴ - 72ab + 81b⁴
