If the roots of the equation `2ax^(3) + (3b-9) x + 1 = 0` are `-2` and 3, then the value of a and b respec-tively are

A

`1/12, 5/18`

B

`(-1)/(12),(-53)/(18)`

C

`(-1)/(12),(-5)/(8)`

D

`(-1)/(12),(55)/(18)`

Text Solution

Verified by Experts

The correct Answer is:
D
Substitute `x = - 2` and `x = 3` to get to equation in a and b then solve for a and b.
