12abx2 -(9a2-8b2)x- 6ab=0 – InterviewSolution

1.

12abx2 -(9a2-8b2)x- 6ab=0

Answer»

Step-by-step explanation:

12abx^2-(9a2-8b^2)x-6ab

NOW WE SHOULD SPLIT THE MIDDLE TERM

12abx^2-9a^2x+8b^2x-6ab

USING FACTORIZATION METHOD

3ax(4bx-3a)+2b(4bx-3a)

(3ax+2b)(4bx-3a)

3ax+2b=0

3ax= -2b

x=-2b/3a

OR

x=3a/4b
