因式分解(x+x)-(x+x-1)-2
(x-1)^3(x+1)(x-2)/(x+4)
x(x+1)(x+2)(x+3)+1 (换元法)
(x+2)(x-2)+16 (x-1)(x-2)+3x(x+3)-4(x+2)(x-3)(x+2)(x-2)+16 (x-1)(x-2)+3x(x+3)-4(x+2)(x-3)
计算 x(x+3)-(x-1)(x-2)
化简:x(2x+1)-x(x-3)

(x+1)(x+2)
x^2(1-x)
计算:(x+2/x^2-2x-x-1/x^2-4x+4)×x/4-x
(x+2/x^2-2x-x-1/x^2-4x+4)/x-4/x因式分解
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
