Find
the root
the
quadratic
equation. Cool by factorizing
(i) 9 x²-3x-2=0​

Answer 1

Answer:

$x = \frac{2}{3} (or) \frac{ - 1}{3}$

Step-by-step explanation:

$9 {x}^{2} - 3x - 2 = 0 \\ = > 9 {x}^{2} + 3x - 6x - 2 = 0 \\ = > 3 {x}(3x + 1) - 2(3x + 1) = 0 \\ = > (3x - 2)(3x + 1) = 0 \\ = > (3x - 2) = 0 \:(or) \: (3x + 1) = 0 \\ = > x = \frac{2}{3} \: (or)x = \frac{ - 1}{3}$
