(6x-3)/(x^2-9x+2)=0

解答

\frac{6 x - 3}{x ^{2} - 9 x + 2} = 0

解答

x = \frac{1}{2}

+1

十进制

x = 0.5

求解步骤

\frac{6 x - 3}{x ^{2} - 9 x + 2} = 0

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

6 x - 3 = 0

将

3

到右边

6 x = 3

两边除以

6

x = \frac{1}{2}

验证解

找到无定义的点（奇点）:

x = \frac{9 + 73}{2}, x = \frac{9 - 73}{2}

将不在定义域的点与解相综合:

x = \frac{1}{2}
