(X-5)(X-6)=X-5
(X-5)(X-6)=X-5
(X-5)(X-6)=X-5
(X-5)(X-6)=X-5
则(x-5)(x-6)-(x-5)=0
则(x-5)(x-6-1)=0
则(x-5)(x-7)=0
所以x=5或x=7
(X-5)(X-6)=X-5
（X-5）(X-6)-1x(X-5)=0
(x-5)(x-6-1)=0
（x-5）（x-7）=0
x1=5 x2=7

解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
2x+3x+4x+5x+x+6x+7x=100
x-4/x-5 - x-5/x-6=x-7/x-8 - x-8/x-9求x=?
(x+7/x+6) +(x+9/x+8)=9x=(x+10/x+9) +(x+6/x+5)
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
已知3x*x-x=1,求6x*x*x+7x*x-5x+2000
(X-5)(X-6)=X-5
3x+5x-6x=?
x^-6x+5=x+4
(x+8)(x+6)(x+7)+(x+5)(x+6)(x+7)=(x+5)(x+8)(x+7)+(x+5)(x+8)(x+6)
用递归法求y=x-(x*x*x/3!)+(x*x*x*x*x/5!)-(x*x*x*x*x*x*x/7!)+.
X(X+5)=6(X+X+5)解一下
x+5/7x=6 x x等于多少
5x/x(1+x)=6/1+x
x平方+5x+6=(x+3)(x+几)
