-16t^2+10t+6=0

解

- 16 t^{2} + 10 t + 6 = 0

解

t = - \frac{3}{8}, t = 1

+1

十進法表記

t = - 0.375, t = 1

解答ステップ

- 16 t^{2} + 10 t + 6 = 0

解くとthe二次式

t_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 ( - 16 ) \cdot 6}{2 ( - 16 )}

1 0^{2} - 4 (- 16) \cdot 6 = 22

t_{1, 2} = \frac{- 10 \pm 22}{2 ( - 16 )}

解を分離する

t_{1} = \frac{- 10 + 22}{2 ( - 16 )}, t_{2} = \frac{- 10 - 22}{2 ( - 16 )}

t = \frac{- 10 + 22}{2 ( - 16 )} : - \frac{3}{8}

t = \frac{- 10 - 22}{2 ( - 16 )} : 1

二次equationの解:

t = - \frac{3}{8}, t = 1
