Hey friend..!! here's your answer
________________________

${9x}^{2} - 3x - 2 \\ \\ a = 9 \\ b = - 3 \\ c = - 2 \\ \\ D = {b}^{2} - 4ac \\ \\D = { (- 3)}^{2} - 4(9)( - 2) \\ \\D = 9 + 72 \\ \\D = 81 \\ \\ \\ x = \frac{ - b + \sqrt{D} }{2a} \: \: or \: \: \frac{ - b - \sqrt{D} }{2a} \\ \\ \\ put \: \: the \: \: values \\ \\ x = \frac{ - ( -3) + \sqrt{81} }{2(9)} \: \: or \: \: \frac{ - ( - 3) - \sqrt{81} }{2(9)} \\ \\ x = \frac{3 + 9}{18} \: \: or \: \: \frac{3 - 9}{18} \\ \\ x= \frac{12}{18} \: \: or \: \: \frac{ - 6}{18} \\ \\ x = \frac{2}{3} \: \: or \: \: - \frac{1}{3}$
