1.5a^2= 6/(a^2)

解答

1.5 a^{2} = \frac{6}{a ^{2}}

解答

a = 2, a = - 2, a = 2 i, a = - 2 i

求解步骤

1.5 a^{2} = \frac{6}{a ^{2}}

在两边乘以

10

15 a^{2} = \frac{60}{a ^{2}}

在两边乘以

a^{2}

15 a^{4} = 60

解

15 a^{4} = 60 : a = 2, a = - 2, a = 2 i, a = - 2 i

a = 2, a = - 2, a = 2 i, a = - 2 i

验证解

找到无定义的点（奇点）:

a = 0

将不在定义域的点与解相综合:

a = 2, a = - 2, a = 2 i, a = - 2 i

x^{- 2} = 7

x^{- 2} = 8

x^{- 2} = 0

(5x)/(x-2)= 1/7

\frac{5 x}{x - 2} = \frac{1}{7}

\frac{51}{21} = \frac{17}{c}
