lim_x→无穷(x3+2x2+x/2x3-x2)
因式分解(1+x+x2+x3)2-x3
x3 -x2- x- 2 因式分解
一、分解因式:x3-x2-x-2
x2+x=1求x3+2x2-7
x1,x2,x3,是x^3+px+2=0的三个根,计算行列式 :|x1 x2 x3| |x2 x3 x1| |x3 x1
分解因式:-27x3+8 ,(x2-5x+2)(x2-5x+4)-24 ,x5+x4+x3+x2+x1+1
3-X2+X-1分之X4+X3-2乘以x3+2x2+2x+2分之X四次方-1除以-2分之X3-X-X2+1化简
证明:(x3+5x2+4x-1)-(-x2-3x+2x3-3)+(8-7x-6x2+x3)的值与x无关.
多项式x3+x2,x2+2x+1,x2-x-2的公因式是 ______.
DIvide x3+x2-14x-24 by x+2
多项式x3+x2,x2+2x+1,x2-1的公因式是______.
(x3-2x2+x-4)-(2x3-5x-4)
