Ответ:
х1=-1 х2=11/3
Объяснение:
[tex]x {}^{2} - \frac{2x - 1}{3} = 2x + 4[/tex]
[tex]3x {}^{2} - 2x + 1 = 6x + 12[/tex]
[tex]3 {x}^{2} - 8x - 11 = 0[/tex]
[tex]d = ( - 8) {}^{2} - 4 \times 3 \times ( - 11) = 196[/tex]
[tex]x1 = \frac{8 + 14}{6} = \frac{22}{6} = \frac{11}{3} [/tex]
[tex]x2 = \frac{8 - 14}{6} = \frac{ - 6}{6} = - 1[/tex]
