苍海一墅独院涨了多少:如何解[2+1/(x-1)-1/(x-1)]/[x-x/(1-x*x)]

如何解[2+1/(x-1)-1/(x-1)]/[x-x/(1-x*x)] 如何解2/x>x+1? 解方程(x+1)(x+2)(x+3)(x+4)=(x+1)(x+1)+(x+2)(x+2)+(x+3)(x+3)+(x+4)(x+4) 5x-3(2x-1)=-4 如何解 5x-3(2x-1)=-4 如何解 x^5-x^4+x^3-x^2+x-1如何因式分解 方程(x+1/x+2)+(x+2/x+3)=(x+3/x+4)+(x+4/x+5)的解 解一元二次方程X*X+1/X*X+X+1/X=0 (x*x*x-x*x+x)/(x*x*x+1)+(x*x+x+1)/[(1-x*x)/x)] (x*x*x-x*x+x)/(x*x*x+1)+(x*x+x+1)/[(1-x*x)/x)]
