0=16.1t^2+57.4413

解答

0 = 16.1 t^{2} + 57.4413

解答

t = \frac{574413}{100 \frac{161}{10}} i, t = - \frac{574413}{100 \frac{161}{10}} i

求解步骤

0 = 16.1 t^{2} + 57.4413

交换两边

16.1 t^{2} + 57.4413 = 0

将

57.4413

到右边

16.1 t^{2} = - 57.4413

两边除以

16.1

t^{2} = - \frac{57.4413}{16.1}

对于

x^{2} = f (a)

解为

x = f (a), - f (a)

t = - \frac{57.4413}{16.1}, t = - - \frac{57.4413}{16.1}

- \frac{57.4413}{16.1} = \frac{574413}{100 \frac{161}{10}} i

- - \frac{57.4413}{16.1} = - \frac{574413}{100 \frac{161}{10}} i

t = \frac{574413}{100 \frac{161}{10}} i, t = - \frac{574413}{100 \frac{161}{10}} i
