Question

х²+х-6/2-х=0 СРОЧНО!​

Answer 1

$\frac{x {}^{2} + x - 6}{2 - x} = 0 \\ x {}^{2} + x - 6 = 0$

а = 1, b = 1, c = -6.

D = b^2-4ac = 1+24 = 25

√D = √25 = 5

$x_{1} = \frac{- b + \sqrt{d}}{2a} = \frac{ - 1 + 5}{2} = 2 \\ x_{2} = \frac{- b - \sqrt{d}}{2a} = \frac{ - 1 - 5}{2} = - 3$

Ответ: 2 ; -3.
