6x²-8x+3x-4=0
[tex]x = \frac{ - b + - \sqrt{b {}^{2} - 4ac} }{2a} \\ \\ 6x {}^{2} - 5x - 4 = 0 \\ \\ a = 6 \\ b = - 5 \\ c = - 4 \\ \\ x = \frac{5 + - \sqrt{25 + 96} }{2 \times 6} \\ \\ x = \frac{5 + - \sqrt{121} }{12} \\ \\ x = \frac{5 + - 11}{12} \\ \\ x1 = \frac{4}{3} \\ \\ x2 = - \frac{1}{2} [/tex]
