12531r^2-4445060.66r+160070813=0

解

12531 r^{2} - 4445060.66 r + 160070813 = 0

解

r = \frac{444506066 + 44450606 6 ^{2} - 8.02339 E 16}{2506200}, r = \frac{444506066 - 44450606 6 ^{2} - 8.02339 E 16}{2506200}

+1

十進法表記

r = 314.05014 \dots, r = 40.67498 \dots

解答ステップ

12531 r^{2} - 4445060.66 r + 160070813 = 0

以下で両辺を乗じる:

100

1253100 r^{2} - 444506066 r + 16007081300 = 0

解くとthe二次式

r_{1, 2} = \frac{- ( - 444506066 ) \pm ( - 444506066 ) ^{2} - 4 \cdot 1253100 \cdot 16007081300}{2 \cdot 1253100}

(- 444506066)^{2} - 4 \cdot 1253100 \cdot 16007081300 = 44450606 6^{2} - 8.02339 E 16

r_{1, 2} = \frac{- ( - 444506066 ) \pm 44450606 6 ^{2} - 8.02339 E 16}{2 \cdot 1253100}

解を分離する

r_{1} = \frac{- ( - 444506066 ) + 44450606 6 ^{2} - 8.02339 E 16}{2 \cdot 1253100}, r_{2} = \frac{- ( - 444506066 ) - 44450606 6 ^{2} - 8.02339 E 16}{2 \cdot 1253100}

r = \frac{- ( - 444506066 ) + 44450606 6 ^{2} - 8.02339 E 16}{2 \cdot 1253100} : \frac{444506066 + 44450606 6 ^{2} - 8.02339 E 16}{2506200}

r = \frac{- ( - 444506066 ) - 44450606 6 ^{2} - 8.02339 E 16}{2 \cdot 1253100} : \frac{444506066 - 44450606 6 ^{2} - 8.02339 E 16}{2506200}

二次equationの解:

r = \frac{444506066 + 44450606 6 ^{2} - 8.02339 E 16}{2506200}, r = \frac{444506066 - 44450606 6 ^{2} - 8.02339 E 16}{2506200}
