Solve each of the following quadratic equations:

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

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

12abx2 - 9a2 x + 8b2x - 6ab = 0


3ax(4bx - 3a) + 2b(4bx - 3a) = 0 taking 3ax common from first two terms and 2b from last two


(4bx - 3a) (3ax + 2b) = 0


(4bx - 3a) = 0 or (3ax + 2b) = 0



Hence the roots of equation are
