x3+7x=9,x=?
5x+(9-x)x3=35
37+x=(9+x)x3
X3+3X+5=7则3X3+9X-2等于多少
X3-3X+1=0 求X3+1/X3
若3x3-x=1 则9x^4+12x3-3x2-7x+2006的值
6x+5x2-3x3+2x-7x3,其中x=-5
设x3+1/x3=2.求x+1/x
X3+X=2 X3为X的立方
若3x3-x=1,求代数式9x4+12x3-3x2-7x=1314的值
若3x3-x=1,则9x4+12x3-3x2-7x+2004的值为
若3x3-x=1,则9x4+12x3-3x2-7x+1999的值为
设3x3-x=1,求9x4+12x3-3x2-7x+2006的值
若3x3-x=1,求多项式9x4+12x3-3x2-7x+2006的值
5.6x+9.2x3=11.6x
(1/5x+x)x3=8
已知x²-8x-3=0,求(x-1)(x3)(x-5)(x-7)
