给出6个整式:x+2,x-2,2x+1,2,x²+x-1,x²-x-11.
(x+1-1/1-x)÷(x-x²/x-1) (x-4/x-x-6+ x+2/x-3)÷x+1/x-3
6x+(2x²-3x)-(x²-1)
x²+3x+9/(x²-27)+6x/(9x-x²)-(x-1)/(6+2x)
根号x²-2x+1(x
|X-1|+|X-2|+|X-3|+|X-4|+|X-5|+|X-6|+|X-7|+|X-8|+|X-9|+|X-10|
当x=2时,求整式x³-2x²-3-4/1(3x³+12x²-8x+4)的值.
当x=-3/2时求整式(2x-1)²-(3x+1)(3x-1)+5x(x-1)
不等式x²-2x-2/x²+x+1
x-1)(X-2)(x-3)...(x-50)+x(x-2)(X-3)...(X-50)+...+x(x-1)(x-2)
化简(x+1/x)²+2(x+1/x)+2
(2x²-2x+3)(-x³+x-1)
(4x³)²×[x³-x(2x-1)]
