(x^4+1)/(2x^2)= 17/8

解答

\frac{x ^{4} + 1}{2 x ^{2}} = \frac{17}{8}

解答

x = 2, x = - 2, x = \frac{1}{2}, x = - \frac{1}{2}

+1

十进制

x = 2, x = - 2, x = 0.5, x = - 0.5

求解步骤

\frac{x ^{4} + 1}{2 x ^{2}} = \frac{17}{8}

使用分式交叉相乘

(x^{4} + 1) \cdot 8 = 34 x^{2}

解

(x^{4} + 1) \cdot 8 = 34 x^{2} : x = 2, x = - 2, x = \frac{1}{2}, x = - \frac{1}{2}

x = 2, x = - 2, x = \frac{1}{2}, x = - \frac{1}{2}

验证解

找到无定义的点（奇点）:

x = 0

将不在定义域的点与解相综合:

x = 2, x = - 2, x = \frac{1}{2}, x = - \frac{1}{2}

流行的例子

\frac{x ^{2} + 1}{2 x} = 2

\frac{x}{6} - \frac{3}{x} = \frac{1}{2}

\frac{x}{2 + 2 x} = x + 3

4/((|x+1|-2))=|x+1|

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

a = \frac{2 m}{s ^{2}}
