5232.6x^2-196250x-15072000=0

解

5232.6 x^{2} - 196250 x - 15072000 = 0

解

x = \frac{1962500 + 196250 0 ^{2} + 3.15463 E 13}{104652}, x = \frac{1962500 - 196250 0 ^{2} + 3.15463 E 13}{104652}

+1

十進法表記

x = 75.60387 \dots, x = - 38.09862 \dots

解答ステップ

5232.6 x^{2} - 196250 x - 15072000 = 0

以下で両辺を乗じる:

10

52326 x^{2} - 1962500 x - 150720000 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 1962500 ) \pm ( - 1962500 ) ^{2} - 4 \cdot 52326 ( - 150720000 )}{2 \cdot 52326}

(- 1962500)^{2} - 4 \cdot 52326 (- 150720000) = 196250 0^{2} + 3.15463 E 13

x_{1, 2} = \frac{- ( - 1962500 ) \pm 196250 0 ^{2} + 3.15463 E 13}{2 \cdot 52326}

解を分離する

x_{1} = \frac{- ( - 1962500 ) + 196250 0 ^{2} + 3.15463 E 13}{2 \cdot 52326}, x_{2} = \frac{- ( - 1962500 ) - 196250 0 ^{2} + 3.15463 E 13}{2 \cdot 52326}

x = \frac{- ( - 1962500 ) + 196250 0 ^{2} + 3.15463 E 13}{2 \cdot 52326} : \frac{1962500 + 196250 0 ^{2} + 3.15463 E 13}{104652}

x = \frac{- ( - 1962500 ) - 196250 0 ^{2} + 3.15463 E 13}{2 \cdot 52326} : \frac{1962500 - 196250 0 ^{2} + 3.15463 E 13}{104652}

二次equationの解:

x = \frac{1962500 + 196250 0 ^{2} + 3.15463 E 13}{104652}, x = \frac{1962500 - 196250 0 ^{2} + 3.15463 E 13}{104652}
