I hope it's correct..
Answer:
(3a + 2b)(3a - 2b + 2)
Step-by-step explanation:
Given Equation is 9a² - 4b² + 2(3a + 2b)
= (3a)² - (2b)² + 2(3a + 2b)
∴ a² - b² = (a + b)(a - b)
= (3a + 2b)(3a - 2b) + 2(3a + 2b)
= (3a + 2b)[3a - 2b + 2]
= (3a + 2b)(3a - 2b + 2).
Factorization of 9a² - 4b² + 2(3a + 2b) = (3a + 2b)(3a - 2b + 2).
Hope it helps!
