(x²+6x-2)(x²+6x-4)+1
化简~(x²+3x+9/x²-27)+(6x/9x-x²)-(x-1/6+2x)
(x²+6x-2)(x²+6x-4)+1
(x²-5x+6分之x²-3x+2)²/(x²-2x-3分之x-1)²
2(x²-1²)
(x-1)(x²+mx+n)=x²-6x²+11x-6
7/x²+x+3/x²-x=6/x²-1
再求代数式(4x²-7x+6y-1)-(-2x²+3y²+2y+2x)+(-6x²
1.(x-2/x+2+6x/x²-4)×(x²-4)
1/X²+3X+2 +1/X²+5X+6 +1/X²+7X+12 +1/X²+9
17²-(8x²+5x)-(4x²+x-3)+(-5x²+6x-1)-3,其中x
3.计算(4X的四次-6X²+2)(5X³-2X²+X-1)
(x²-2x)²+2x²-4x+1
