0=-4.8992x^2+2.624x+0.00003

解

0 = - 4.8992 x^{2} + 2.624 x + 0.00003

解

x = - \frac{- 2.624 + 6.88596 \dots}{9.7984}, x = \frac{2.624 + 6.88596 \dots}{9.7984}

+1

十進法表記

x = - 0.00001 \dots, x = 0.53560 \dots

解答ステップ

0 = - 4.8992 x^{2} + 2.624 x + 0.00003

辺を交換する

- 4.8992 x^{2} + 2.624 x + 0.00003 = 0

解くとthe二次式

x_{1, 2} = \frac{- 2.624 \pm 2.62 4 ^{2} - 4 ( - 4.8992 ) \cdot 0.00003}{2 ( - 4.8992 )}

2.62 4^{2} - 4 (- 4.8992) \cdot 0.00003 = 6.88596 \dots

x_{1, 2} = \frac{- 2.624 \pm 6.88596 \dots}{2 ( - 4.8992 )}

解を分離する

x_{1} = \frac{- 2.624 + 6.88596 \dots}{2 ( - 4.8992 )}, x_{2} = \frac{- 2.624 - 6.88596 \dots}{2 ( - 4.8992 )}

x = \frac{- 2.624 + 6.88596 \dots}{2 ( - 4.8992 )} : - \frac{- 2.624 + 6.88596 \dots}{9.7984}

x = \frac{- 2.624 - 6.88596 \dots}{2 ( - 4.8992 )} : \frac{2.624 + 6.88596 \dots}{9.7984}

二次equationの解:

x = - \frac{- 2.624 + 6.88596 \dots}{9.7984}, x = \frac{2.624 + 6.88596 \dots}{9.7984}

2 x^{2} - 3 = 3 x^{2} + 1

x^{2} - 44 x + 1681 = 0

2 x^{2} - 3 x = 10

x (2 x + 5) = 4 (x + 7)

10x^2+10x^2+1=0

10 x^{2} + 10 x^{2} + 1 = 0
