-1/100 x^2+1600=0

解答

- \frac{1}{100} x^{2} + 1600 = 0

解答

x = 400, x = - 400

求解步骤

- \frac{1}{100} x^{2} + 1600 = 0

将

1600

到右边

- \frac{1}{100} x^{2} = - 1600

在两边乘以

- 100

x^{2} = 160000

对于

x^{2} = f (a)

解为

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

x = 160000, x = - 160000

160000 = 400

- 160000 = - 400

x = 400, x = - 400
