3x² + 5x - 2 = 0

3x² + 3x + 2x + 2 = 0

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

X = -2 / 3 , -1


wardahd1234: it is wrong
paryuljain23: ok
wardahd1234: you have by mistake taken +2 instead of -2

3 {x}^{2}  + 5x - 2 \\  = 3 {x}^{2}  + 6x - x - 2 \\  = 3x(x + 2) - 1(x + 2) \\  = (3x - 1)(x + 2) \\ x =  \frac{1}{3} x =  - 2
