(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)
lim( x→∞)(1+x / x)^3x
x+(x+1)/3
(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
1/x(x+3)+1/(x+3)(x+6)+---+1/(x+27)(x+30)
(x-1/x+1 - x+1/x-3 )除 2/x²+2x+1
3/x-1=4/x 6/x+1=x+5/x(x+1)
