x-6/(4-4x+x^2)除以(x+3)乘以1/3-x

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 *-----------------------------------------------*| 6 4 X | 8 X X | X X 5 || X X X | X X X | X 7 8 || X X X | X X X | X X X ||---------------+---------------+--------------- || X X X | X X X | 5 1 X || X X X | X 6 X | X X X || 8 X X | 3 5 X | 2 X X || (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
