Question

Factorise 9a square +3a -8b -64b square

Answer 1

Answer:

(3a - 8b)(3a +8b +1)

Step-by-step explanation:

Given : 9a² + 3a - 8b - 64b²

On factorising it, we get :-

=> 9a² - 64b² + 3a - 8b = [(3a)² - (8b)²] + (3a - 8b)

                                      = (3a + 8b)(3a - 8b) + (3a - 8b)

                                       = (3a - 8b)(3a +8b +1)
