Question

x(в квадрате)-4/8 -2x+3/3=-1

Answer 1

Объяснение:

${x}^{2} - \frac{4}{8} - 2x + \frac{3}{3} = - 1 \\ {x}^{2} - 2x - \frac{4}{8} + 1 + 1 = 0 \\ {x}^{2} - 2x + \frac{ - 4 + 8 + 8}{8} = 0 \\ {x}^{2} - 2x + \frac{12}{8} = 0 \\ {x}^{2} - 2x + \frac{3}{2} = 0 \\ 2 {x}^{2} - 4x + 3 = 0 \\ dis = 16 - 24 = - 8 \\ dis < 0 \\ net \: korney$
