x3+5x-6x3+5x-6x3+5x-6x^3+5x-6=x^3-x^2+x^2+5x-6=x^2(x-1)+(x+6)(x-1)=(x^2+x+6)(x-1)你好:x^3+5x-6=0=(x^3-
x3+5x-6
x3+5x-6
x3+5x-6
x^3+5x-6
=x^3-x^2+x^2+5x-6
=x^2(x-1)+(x+6)(x-1)
=(x^2+x+6)(x-1)
你好:
x^3+5x-6=0
=(x^3-1)+(5x-5)
=(x-1)(x^2+x+1)+5(x-1)
=(x-1)(x^2+x+6)=0
(x-1)(x+6)
是x²+5x-6吧?
x²+5x-6
=(x+6)(x-1)

1.证明(8-7x-6x2+x3)+(x3+5x2+4x-1)-(-x2-3x+2x3-3)的值与x无关.快,
求证:无论X取何值下列(8-7X-6X2+X3)+(X3+5X2+4X-1)-(-X2-3X+2X3-3)结果不变
