0=-16t^2+16t+370

解答

0 = - 16 t^{2} + 16 t + 370

解答

t = - \frac{- 2 + 374}{4}, t = \frac{2 + 374}{4}

+1

十进制

t = - 4.33476 \dots, t = 5.33476 \dots

求解步骤

0 = - 16 t^{2} + 16 t + 370

交换两边

- 16 t^{2} + 16 t + 370 = 0

使用求根公式求解

t_{1, 2} = \frac{- 16 \pm 1 6 ^{2} - 4 ( - 16 ) \cdot 370}{2 ( - 16 )}

1 6^{2} - 4 (- 16) \cdot 370 = 8374

t_{1, 2} = \frac{- 16 \pm 8 374}{2 ( - 16 )}

将解分隔开

t_{1} = \frac{- 16 + 8 374}{2 ( - 16 )}, t_{2} = \frac{- 16 - 8 374}{2 ( - 16 )}

t = \frac{- 16 + 8 374}{2 ( - 16 )} : - \frac{- 2 + 374}{4}

t = \frac{- 16 - 8 374}{2 ( - 16 )} : \frac{2 + 374}{4}

二次方程组的解是:

t = - \frac{- 2 + 374}{4}, t = \frac{2 + 374}{4}
