1/5x+5+1/5x+5+17=x
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)
提取公因式:已知x*x-5x+1=0 求x*x*x-4x*x-4x-1
已知3x*x-x=1,求6x*x*x+7x*x-5x+2000
x+2/x+1-x+3/x+2-x+4/x+3+x+5/x+4
6/x+1=x-5/x^2+x
X-5+8*X=7*X-2*X-1
5/x²+x-1/x²-x=0
(2x-1)/(x-1)(x-2)=(x-5)/(x-2)(x-3) x/2x^2-11x-21=(x+7)/x^2-1
