(a^2-3a+2)x^2+(2a^2+4a+1)xy+(a^2-a)y^2因式分解,谢谢了!
是(2a^2-4a+1)。。。。。。不过答案貌似都不对.....

解答
(a²-3a+2)x²+(2a²-4a+1)xy+(a²-a)y²
=(a-1)(a-2)x²+(2a²-4a+1)xy+a(a-1)y²
=[(a-1)x+ay]*[(a-2)x+(a-1)y]

因式分解(x+a)(x+2a)(x+3a)(x+4a)+a^4
(x+a)(x+2a)(x+3a)(x+4a)+a^4如何因式分解?
因式分解:(a^2-4a)^2+(3a-12)^2
因式分解:(a+1)^2-(3a^2-4a)^2 急
(a^2-3a+2)x^2+(2a^2-4a+1)xy+(a^2-a)y
must后面跟动词原形吗?
