150000000x^2+x-0.29=0

解

150000000 x^{2} + x - 0.29 = 0

解

x = \frac{- 100 + 1740000010000}{30000000000}, x = \frac{- 100 - 1740000010000}{30000000000}

+1

十進法表記

x = 0.00004 \dots, x = - 0.00004 \dots

解答ステップ

150000000 x^{2} + x - 0.29 = 0

以下で両辺を乗じる:

100

15000000000 x^{2} + 100 x - 29 = 0

解くとthe二次式

x_{1, 2} = \frac{- 100 \pm 10 0 ^{2} - 4 \cdot 15000000000 ( - 29 )}{2 \cdot 15000000000}

10 0^{2} - 4 \cdot 15000000000 (- 29) = 1740000010000

x_{1, 2} = \frac{- 100 \pm 1740000010000}{2 \cdot 15000000000}

解を分離する

x_{1} = \frac{- 100 + 1740000010000}{2 \cdot 15000000000}, x_{2} = \frac{- 100 - 1740000010000}{2 \cdot 15000000000}

x = \frac{- 100 + 1740000010000}{2 \cdot 15000000000} : \frac{- 100 + 1740000010000}{30000000000}

x = \frac{- 100 - 1740000010000}{2 \cdot 15000000000} : \frac{- 100 - 1740000010000}{30000000000}

二次equationの解:

x = \frac{- 100 + 1740000010000}{30000000000}, x = \frac{- 100 - 1740000010000}{30000000000}

2 x^{2} = - 72

solvefor p,4x^2-9=(px+t)(px-t)

so l v e f or p, 4 x^{2} - 9 = (p x + t) (p x - t)
