(-3x³)²-[(2x)²]³
3x³-2x*x²
因式分解x+3x³+x²-3x-2
(2x²-2x+3)(-x³+x-1)
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
因式分解:x³-2x²+x
2f(x)+x^2f(1/x)=(3x³-x²+4x+3)/(x+1) 2x²f(1/x)
2x^6×x³-3x^9+5x²×x^7等于多少
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
(4x³)²×[x³-x(2x-1)]
