F(X)=(1 + x)^ 2-2ln(1 + X),点击看详细全都寻求指导,所以:点击看详细F'(x)的= 2(1 + X)-2 * 1 /(1 + X)= 2X + 2-2 /(X + 1),点击看详细看到更多的基本功能的推导,以及两个函数的总和,差,乘积,商.点击看详细衍生和其他复杂的功能,教科书

解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
x(x-2)-2x(x+1)-3x(x-5) 其中x=负½
(x-3/x-2)-(x-2/x-1)=(x-5/x4) -(x-4/x-3)
x-1分之x²+5x - x²-x分之2x²+4x
x(x+1)+(x+2)+(x+3)+(x+4)+(x+5) = 27求x
】x(x+1)+x^2(x-1)
f(x,-x)=x^2+2x,fx(x,-x)=5x+1,则fy(x,-x)=
