(a^3(2a-x))/(2(a-x)^2)=3a^2

解答

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

x = \frac{a}{2}, x = \frac{4 a}{3}; a \neq = 0

求解步骤

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

在两边乘以

2 (a - x)^{2}

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

解

a^{3} (2 a - x) = 6 a^{2} (a - x)^{2} : x = \frac{a}{2}, x = \frac{4 a}{3}; a \neq = 0

x = \frac{a}{2}, x = \frac{4 a}{3}; a \neq = 0

\frac{x}{x} = 2 n^{2} + 1 -, 3 < n < 3

so l v e f or x, \frac{1}{x} + \frac{y}{3} = \frac{5}{6}

\frac{1}{y} + \frac{2}{y} = \frac{3}{y}

so l v e f or x, y = \frac{( 2 y + x )}{x}
