分解因式:2a(x^2+1)^2-2ax^2分解因式:2a(x^2+1)^2-2ax^2分解因式:2a(x^2+1)^2-2ax^22a(x^4+X^2+1)2a(x^2+1)^2-2ax^2=2a(

分解因式:2a(x^2+1)^2-2ax^2
分解因式:2a(x^2+1)^2-2ax^2

分解因式:2a(x^2+1)^2-2ax^2
2a(x^4+X^2+1)

2a(x^2+1)^2-2ax^2
=2a(x^4+2x^2+1)-2ax^2
=2ax^4+4ax^2+2a-2ax^2
=2ax^4+2ax^2+2a
=2a(x^4+x^2+1)
有理数范围内的因式分解就到此为止

=2a(x^4+2x^2+1)-2ax^2
=2a(x^4+2x^2+1-x^2)
=2a(x^4+x^2+1)
