(2x²)³÷x²-2x³×3x
3x³-2x*x²
(2x²-2x+3)(-x³+x-1)
因式分解x+3x³+x²-3x-2
先化解,在求值;(3x/x-1-x/x+1)÷x四次方-4x²/x³-x,其中x=根号2+2
因式分解:x³-2x²+x
解不等式[2x³(x+3)-x²]÷2x²<-x(3-x)
(x+1-1/1-x)÷(x-x²/x-1) (x-4/x-x-6+ x+2/x-3)÷x+1/x-3
4x²-1/3x²-x·9x³-x/2x^4-x³计算 急
(1-x/3-x)²/(3-2x-x²/9-x²)³*(x²/x
1.(x²-9)/(x²+2x²+x)*(3x³+9x²)/(x
3x³·x^9+x²·x^10-2x·x³·x^8计算
(4x³)²×[x³-x(2x-1)]
