(6x^2-(3a))/(2*x-a^2)=0

解答

\frac{6 x ^{2} - ( 3 a )}{2 \cdot x - a ^{2}} = 0

x = \frac{a}{2}, x = - \frac{a}{2}

求解步骤

\frac{6 x ^{2} - ( 3 a )}{2 x - a ^{2}} = 0

化简

\frac{6 x ^{2} - ( 3 a )}{2 x - a ^{2}} : \frac{6 x ^{2} - 3 a}{2 x - a ^{2}}

\frac{6 x ^{2} - 3 a}{2 x - a ^{2}} = 0

\frac{f ( x )}{g ( x )} = 0 \Rightarrow f (x) = 0

6 x^{2} - 3 a = 0

解

6 x^{2} - 3 a = 0 : x = \frac{a}{2}, x = - \frac{a}{2}

x = \frac{a}{2}, x = - \frac{a}{2}

so l v e f or k, x = \frac{1}{k}

\frac{( x - 1 )}{( x - 2 )} + \frac{( x - 3 )}{( x - 4 )} = \frac{31}{3}

x^{- 3} = 125

\frac{x ^{2} - 4}{x ^{2}} = 3

\frac{1}{( x ^{2} + 1 )} + \frac{1}{( x - 1 )} = \frac{6}{5}
