|X-1|+|X-2|+|X-3|+|X-4|+|X-5|+|X-6|+|X-7|+|X-8|+|X-9|+|X-10|
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
(x+2/x^2-x-6)-(2x/x^2-3x)-(x+1/x^2-6x+9)
x+2/x^2-x-6 + 2x/x^3-3x - x+1/x^2-6x+9
(5x+1)X(6x+2)
因式分解:x(x-1)(x-2)-6
(x+1-1/1-x)÷(x-x²/x-1) (x-4/x-x-6+ x+2/x-3)÷x+1/x-3
(x-6)×(x-3) (x+2/1)×(x-3/1)
1/(x+3)-(x-2)/(x^2-5x+6)
X^2+X分之6=X^2+X+1
x^8+x^6+x^4+x^2+1因式分解
6/x+1=x-5/x^2+x
