128= 2/1125 q^2+40

解答

128 = \frac{2}{1125} q^{2} + 40

解答

q = 3055, q = - 3055

+1

十进制

q = 222.48595 \dots, q = - 222.48595 \dots

求解步骤

128 = \frac{2}{1125} q^{2} + 40

交换两边

\frac{2}{1125} q^{2} + 40 = 128

将

40

到右边

\frac{2}{1125} q^{2} = 88

在两边乘以

1125

2 q^{2} = 99000

两边除以

2

q^{2} = 49500

对于

x^{2} = f (a)

解为

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

q = 49500, q = - 49500

49500 = 3055

- 49500 = - 3055

q = 3055, q = - 3055

2x^1-3x^2=-2,4x^1-12x^2=4

2 x^{1} - 3 x^{2} = - 2, 4 x^{1} - 12 x^{2} = 4

completesquare x^2+3x-9=0

p^{2} = 6 p - 4

m^{2} + 3 - 12 m = 0

x^{2} - 2 = 2 + 2 x - x^{2}
