X-(X-2)×3/10-1/2X=2
x+2/x+3-x+1/x+2=x+8/x+9-x+7/x+8
X-2分之X=X-5分之X-4怎么解?还有X减3分之X等于X减1分之X+1
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
计算:2x/(x-2)(x+1)÷(1-x/x+1)-x²+2x/x²-4?
x(2x-1)=-3x(x+1)+5x²+3
y=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10)的导数在x=1
|X-1|+|X-2|+|X-3|+|X-4|+|X-5|+|X-6|+|X-7|+|X-8|+|X-9|+|X-10|
设函数f(x)=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10),
解分式方程3/x-1+4x/1-x^2=-1/x+1
2(x² +1÷x²)-3(x +1÷x)=1
(x+1 )分之 3x² - x² 分之(x+1)=2
4x-2=3x+1 -x+3=10 x-7=11-x x=四分之一x+6
