16.1t^2+200t-200=0

解

16.1 t^{2} + 200 t - 200 = 0

解

t = \frac{20 ( 3305 - 50 )}{161}, t = - \frac{20 ( 50 + 3305 )}{161}

+1

十進法表記

t = 0.93032 \dots, t = - 13.35268 \dots

解答ステップ

16.1 t^{2} + 200 t - 200 = 0

以下で両辺を乗じる:

10

161 t^{2} + 2000 t - 2000 = 0

解くとthe二次式

t_{1, 2} = \frac{- 2000 \pm 200 0 ^{2} - 4 \cdot 161 ( - 2000 )}{2 \cdot 161}

200 0^{2} - 4 \cdot 161 (- 2000) = 403305

t_{1, 2} = \frac{- 2000 \pm 40 3305}{2 \cdot 161}

解を分離する

t_{1} = \frac{- 2000 + 40 3305}{2 \cdot 161}, t_{2} = \frac{- 2000 - 40 3305}{2 \cdot 161}

t = \frac{- 2000 + 40 3305}{2 \cdot 161} : \frac{20 ( 3305 - 50 )}{161}

t = \frac{- 2000 - 40 3305}{2 \cdot 161} : - \frac{20 ( 50 + 3305 )}{161}

二次equationの解:

t = \frac{20 ( 3305 - 50 )}{161}, t = - \frac{20 ( 50 + 3305 )}{161}
