分解因式x²-(4a-1)x+3a²-a

分解因式x²-(4a-1)x+3a²-a
分解因式x²-(4a-1)x+3a²-a

分解因式x²-(4a-1)x+3a²-a
x2-(4a-1)x+3a2-a=(x-3a+1)(x-a)

x²-(4a-1)x+3a²-a
=x²-(4a-1)x+a(3a-1)
=[x-(3a-1)](x-a)
=(x-3a+1)(x-a)
采纳

(X-3a)[X-(a-1)]

x²-(4a-1)x+3a²-a
3a²-(4x+1)a+x²+x
(a-x)(3a-x-1)
这样就可以了

x²-(4a-1)x+3a²-a
=x²-3ax+x+3a²-a-ax
=x(x-3a+1)-a(x-3a+1)
=(x-3a+1)(x-a)
