计算[3x分之2-(x+y分之2)乘以[3x分之x+(y-x^2-xy)]除以x分之x-y
计算[3x分之2-(x+y分之2)乘以[3x分之x+(y-x^2-xy)]除以x分之x-y
[3x分之2-(x+y分之2)乘以[3x分之x+(y-x^2-xy)]除以x分之x-y
{2/3x-2/(x+y)*[x/3x+(y-x²-xy)]}÷(x-y)/x
题目错了吧?
再问: {3x分之2-(x+y分之2)乘以(3x分之x+y)-(x^2)-(xy)}除以x分之x-y
再答: {3x分之2-(x+y分之2)乘以(3x分之x+y)-(x^2)-(xy)}除以x分之x-y={2/3x-2/(x+y)*(x+y)/3x-x²-xy}÷(x-y)/x=(2/3x-2/3x)-x²-xy)*x/(x-y)=-x(x+y)*x/(x-y)=-x²(x+y)/(x-y)
