0.01x^2+0.2-0.6=0

解答

0.01 x^{2} + 0.2 - 0.6 = 0

解答

x = 210, x = - 210

+1

十进制

x = 6.32455 \dots, x = - 6.32455 \dots

求解步骤

0.01 x^{2} + 0.2 - 0.6 = 0

将

0.2

到右边

0.01 x^{2} - 0.6 = - 0.2

将

0.6

到右边

0.01 x^{2} = 0.4

两边除以

0.01

x^{2} = 40

对于

x^{2} = f (a)

解为

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

x = 40, x = - 40

40 = 210

- 40 = - 210

x = 210, x = - 210
