30.252x^2-1290x+2946.667=0

解

30.252 x^{2} - 1290 x + 2946.667 = 0

解

x = \frac{1290000 + 129000 0 ^{2} - 356570280336}{60504}, x = \frac{1290000 - 129000 0 ^{2} - 356570280336}{60504}

+1

十進法表記

x = 40.22002 \dots, x = 2.42177 \dots

解答ステップ

30.252 x^{2} - 1290 x + 2946.667 = 0

以下で両辺を乗じる:

1000

30252 x^{2} - 1290000 x + 2946667 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 1290000 ) \pm ( - 1290000 ) ^{2} - 4 \cdot 30252 \cdot 2946667}{2 \cdot 30252}

(- 1290000)^{2} - 4 \cdot 30252 \cdot 2946667 = 129000 0^{2} - 356570280336

x_{1, 2} = \frac{- ( - 1290000 ) \pm 129000 0 ^{2} - 356570280336}{2 \cdot 30252}

解を分離する

x_{1} = \frac{- ( - 1290000 ) + 129000 0 ^{2} - 356570280336}{2 \cdot 30252}, x_{2} = \frac{- ( - 1290000 ) - 129000 0 ^{2} - 356570280336}{2 \cdot 30252}

x = \frac{- ( - 1290000 ) + 129000 0 ^{2} - 356570280336}{2 \cdot 30252} : \frac{1290000 + 129000 0 ^{2} - 356570280336}{60504}

x = \frac{- ( - 1290000 ) - 129000 0 ^{2} - 356570280336}{2 \cdot 30252} : \frac{1290000 - 129000 0 ^{2} - 356570280336}{60504}

二次equationの解:

x = \frac{1290000 + 129000 0 ^{2} - 356570280336}{60504}, x = \frac{1290000 - 129000 0 ^{2} - 356570280336}{60504}
