6n^2+10n+25=5n^2

解

6 n^{2} + 10 n + 25 = 5 n^{2}

n = - 5

解答ステップ

6 n^{2} + 10 n + 25 = 5 n^{2}

5 n^{2}

を左側に移動します

n^{2} + 10 n + 25 = 0

解くとthe二次式

n_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 \cdot 1 \cdot 25}{2 \cdot 1}

1 0^{2} - 4 \cdot 1 \cdot 25 = 0

n_{1, 2} = \frac{- 10 \pm 0}{2 \cdot 1}

n = \frac{- 10}{2 \cdot 1}

\frac{- 10}{2 \cdot 1} = - 5

n = - 5

二次equationの解:

n = - 5
