怎样吧x^5-4x+3变成(x-1)乘以另一个公因式的形式

楼上的有错,他的结果=x^5-3x-x^4+3

x^5-4x+3
=X^5-x-(3x-3)
=x^5-x-3(x-1)
=x(x^4-1)-3(x-1)
=x(x^2+1)(x^2-1)-3(x-1)
=x(x^2+1)(x+1)(x-1)-3(x-1)
=(x-1)[x(x^2+1)(x+1)-3]
应该是这样了。。

x^5-4x+3
=x^5-x-(3x-3)
=x(x^4-1)-3(x-1)
=x(x^2+1)(x^2-1)-3(x-1)
=x(x^2+1)(x+1)(x-1)-3(x-1)
=[x(x^2+1)(x+1)-3]*(x-1)
=(x-1)(x^4+x^3+x^2+x-3)

x^5-4x+3
=X^5-x-(3x-3)
=x^5-x-3(x-1)
=x(x^4-1)-3(x-1)
=x(x^2+1)(x^2-1)-3(x-1)
=x(x^2+1)(x+1)(x-1)-3(x-1)
=(x-1)[x(x^2+1)(x+1)-3]
=(x-1)[(x^3+x)(x+1)-3]
=(x-1)(x^4+x^3+x^2+x-3)

x^5-4x+3
=x^5-x-(3x-3)
=x^4(x-1)-3(x-1)
=(x-1)(x^4-3)

x^5-4x+3
=X^5-x-(3x-3)
=x^5-x-3(x-1)
=x(x^4-1)-3(x-1)
=x(x^2-1)(x^2+1)-3(x-1)
=x(x-1)(x+1)(x^2+1)-3(x-1)
=(x-1)[x(x+1)(x^2+1)-3]

公因式?
因式吧?

直接除就找到了,综合除法快点,另一个因式答案:x^4+x^3+x^2+x-3
