# 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
