Answer:
Step-by-step explanation:
3a² - ab - 14b²
3ab² x -14b²
= -42a²b²
-7ab and +6ab
= 3a² - 7ab +6ab - 14b²
= a(3a - 7b) + 2b(3a - 7b)
= (a + 2b)(3a - 7b)

Answer :
- We have to factorise it
- Solve it using middle term splitting method.
= 3a²-ab-14b²
= 3a²+6ab - 7ab -14b²
= 3a(a + 2b) -7b(a + 2b)
= (a + 2b) ( 3a - 7)
Thus, your answer is (a + 2b) ( 3a - 7) respectively !
