Answer 1

Answer:

(6x + 4a+3b)(6x - 4a -3b)

Step-by-step explanation:

36x² - 16a² - 24ab - 9b²

= 36x² - (16a² + 24ab+9b²)

Since 16a² + 24ab+9b² is nothing but (4a)² + 2*4a*3b + (3b)² = (4a+3b)²

= 36x² - (4a+3b)²

= (6x)² - (4a+3b)²

The above is of form a² - b² and we know that it is equal to (a+b)(a-b)

= (6x + 4a+3b)(6x - 4a -3b)
