solvefor x,x^2+12x=-36

解

x, x^{2} + 12 x = - 36

x = - 6

解答ステップ

x^{2} + 12 x = - 36

36

を左側に移動します

x^{2} + 12 x + 36 = 0

解くとthe二次式

x_{1, 2} = \frac{- 12 \pm 1 2 ^{2} - 4 \cdot 1 \cdot 36}{2 \cdot 1}

1 2^{2} - 4 \cdot 1 \cdot 36 = 0

x_{1, 2} = \frac{- 12 \pm 0}{2 \cdot 1}

x = \frac{- 12}{2 \cdot 1}

\frac{- 12}{2 \cdot 1} = - 6

x = - 6

二次equationの解:

x = - 6
