[(x^2+1)^2-4x(x^2+1)+4x^2]/(x-1)^2 计算
如何计算 (x+1)(x+2)(x+3)(x+4)
计算(X-1)(X-2)(X-3)(X-4)
分式计算:(x+2)/(x^2-2x)-(x-1)/(x^2-4x+4)
(x-1)(x^2+x+1)-x(x^2-2x+4)计算
计算:(x-1)(x^2-4X+3)-x(x^2-5X+2)有过程
x+2/x²-2x-x-1/x²-4x+4计算
计算:2x/(x-2)(x+1)÷(1-x/x+1)-x²+2x/x²-4?
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
计算(x+/1x)(x^2+1/x^2)(x^4+1/x^4)(x^8+1/x^8)(x^16+1/x^16)(x^2-
x+2/x+1-x+3/x+2-x+4/x+3+x+5/x+4
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
计算(x+4)·(-2x)-(x+1)(x-1)+(-3x+2)(x+1); (3x-y)(y+3x)-(4x-3x)(
