Question

pls solve this question

$9 {x }^{2} - 3x - 2 = 0$

Answer 1

Hey , your answer is here.....

$9 {x }^{2} - 3x - 2 = 0$

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

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

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

3x - 2 = 0 or 3x + 1 = 0

3x = 2 or 3x = -1

x = 2/3 or x = -1/3


So , X = 3/2 or X = -1/3


Hope it helps u.....
