x-6/(4-4x+x^2)除以(x+3)乘以1/3-x
x-6/(4-4x+x^2)除以(x+3)乘以1/3-x
x-6/(4-4x+x^2)除以(x+3)乘以1/3-x
(x^2-4x-2)(1-3x)/3(2-x)^2(x+3)
6除以x+1=x+5除以3-2x=4搞错了,应该 是6除以x+1=x+5除以x(x+1)
x-6/(4-4x+x^2)除以(x+3)乘以1/3-x
x^2+6x+9/x-2除以x+3/x^2-4
计算:2x-6/4-4x+x^2除以(x+3)乘以x^2+x-6/x+3
计算:(2x-6)/(4-4x+x^2)除以(x+3)乘以(x^2+x-6)/(3-x)
4-4x+x^2分之2x-6除以(x+3)乘以3-x分之x^2+x-6
2x-6分之4-4x+x²除以(x+3)乘以x²+x-6分之3-x
2x-6/4-4x+x的平方除以(x+3)*x平方+x-6/3-x
(x^2-x-6分之x^2-4+x-3分之x+2)除以x-3分之x+1
化简(2x-6)除以(X平方-4x+4)除以(x+3)乘以(x平方+x-6)除以(12-4x)
化简(2x-6)除以(X平方-4x+4)除以(x+3)乘以(x平方+x-6)除以(3-x)
xy²/(x²y-y) × x²/(x²+x)=(x²-3x)/(x²-5x) × 2x-10/(x²-6x+9)=化简求植x²-1/(x²-x-2)除以x/2x-4,其中x=1/2[x-x/(x+1)]除以[x/(2x-4)] ,其中x=√2+1

(2x-6)除以(X平方-4x+4)乘以(2x-4)除以(x-3)算出来
求值:(x/x^2-1)除以(x^2+4x+3)/(x^2+2x+1)
[x(-4x+3)+(x+2)(x-2)x]除以(-x)
2x-6/x^2-4x+4除以12-4x/x^2+5X-6除以x^2+5x+6/x^2-5x-6
1.【x-1分之x平方+3x+2】+【6分之2+x-x平方】-【10-x分之4-x平方】2.【x+1-1分之1-x】除以【x-x平方分之x-1】3.【x平方-4分之x平方-x-6】+【x+2分之x-3】这个结果再除以【x+1分之x-3】4.【x分之x-y】乘以
