Q. 2 B5.0( 2 Votes )

Solve the following equations by factorization method:

9x2 – 3x – 2 = 0

Answer :

On factorizing the above equation,

9x2 – 3x - 2 = 0


9x2 + 3x -6x - 2 = 0


3x(3x + 1) – 2(3x + 1) = 0


(3x - 2) (3x + 1) = 0


Solving the first part,


3x - 2 = 0


3x = 2


x = 2/3


Solving the second part,


3x + 1 = 0


3x = -1


x = -1/3
