请问这道题咋做 :(x)X (x+1) X (x+2) X (x+3) =360
35道.符号^代表平方.读起来就是(X的平方).1,x^-x-202,x^-9x+203,x^-9x-204,x^+9x+205,x^-18x+326,x^+14x-317,x^+18x+328,x^+14x-329,x^+19x+4810,x^+47x-4811,x^+13x-4812,x^+2x-4813,x^+26x+4814,x^-22x-4815,x^+17x+7216,x^+21x-10017,x^-x-7218,x
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)
计算 x(x+3)-(x-1)(x-2)
化简:x(2x+1)-x(x-3)
(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)

x^2(1-x)
(x+1)(x+2)(x+3)(x+4)+1(x+1)(x-2)(x+3)(x-4)+25
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
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
化简[(x+2)/(x²-2x)+(x-1)/(x²-4x+4)]除以(x-4)/x
[(x+2)/(x²+2x)-(x-1)/(x²-4x+4)]÷(x-4)/x
解方程:x(x-1)+x(2+x)=2x(x-2)
