x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
已知x-x-1=0,证明.x=2x+1,x的五次方=5x+3.
解下列方程..1.(x/x-5)=(x-2)/(x-3)2.(6x-1)/(3x+2)=(4x-7)/(2x-5)3.{
计算:1.6x-1/3x+2=5x-7/2x-5 2.2x/x-1=2/x+2=2 3.x-1/x+1-x/x-1=4/
6/x+1=x-5/x^2+x
X-5+8*X=7*X-2*X-1
(2x-1)/(x-1)(x-2)=(x-5)/(x-2)(x-3) x/2x^2-11x-21=(x+7)/x^2-1
y=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10)的导数在x=1
已知1+x+x^2+x^3=0,求x+x^2+x^3+x^4+x^5+x^6+x^7+x^8的值
解方程(x-6)(x^2+x+1)-x(x+1)(x-1)=x(2-5x)
