Решите квадратное уравнение: x^2+5x-6=0.

\[x^{2} + 5x - 6 = 0\]

\[D = 5^{2} - 4 \cdot 1 \cdot ( - 6) =\]

\[= 25 + 24 = 49\]

\[x_{1} = \frac{- 5 + \sqrt{49}}{2} = \frac{- 5 + 7}{2} = \frac{2}{2} =\]

\[= 1\]

\[x_{2} = \frac{- 5 - \sqrt{49}}{2} = \frac{- 5 - 7}{2} =\]

\[= \frac{- 12}{2} = - 6\]

\[Ответ:1;\ - 6.\]
