回答1:

解:提取公因式(x²+1)(x²+1一2)=(x²十1)(x十1)(x一1)

回答2:

(x²+1)²-2(x²+1)
= x^4 + 2x^2 + 1 - 2x^2 - 2
= x^4 - 1
= ( x²+1 )( x²-1 )

= ( x²+1 )( x+1 )( x-1 )

回答3:

解:(x²+1)²-2(x²+1)=(x²+1-2)(x²+1)=(x²-1)(x+1)=x⁴-1

回答4:

(x²+1)²-2(x²+1)
=(x²+1)[(x²+1)-2]
=(x²+1)(x²-1)
=(x²+1)(x-1)(x+1)

回答5:

(x²+1)²-2(x²+1)
=(x²+1)(x²+1-2)
=(x²+1)(x+1)(x-1)
