(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
(x+2/x+1)-(x+4/x+3)-(x+3/x+2)+(x+5/x+4)
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
化简 x(x-1)+2x(x+1)-3x(2x-5)
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
x(x平方-1)+2X平方(X+1)-3X(2X-5)帮个忙
[x(x+1)+x平方(x-1)]+(-3x)
(x-1)/x -(1-x)/(x+1)=(5x-5)/(2x+2) x等于多少
(x-1)^3(x+1)(x-2)/(x+4)
(x+1)(x+2)(x+3)(x+4)+1
计算 x(x+3)-(x-1)(x-2)
解方程(x-2)X(x的平方-6x-9)=x(x-5)X(x-3)
