1.因式分解3a^3b^2c－6a^2b^2c^2＋9ab^2c^3＝3ab^2 c(a^2-2ac+3c^2)
2.因式分解xy＋6－2x－3y＝(x-3)(y-2)
3.因式分解x^2(x－y)＋y^2(y－x)＝(x+y)(x-y)^2
4.因式分解2x^2－(a－2b)x－ab＝(2x-a)(x+b)
5.因式分解a^4－9a^2b^2＝a^2(a+3b)(a-3b)
8.因式分解ab(x^2－y^2)＋xy(a^2－b^2)＝(ay+bx)(ax-by)
9.因式分解(x＋y)(a－b－c)＋(x－y)(b＋c－a)＝2y(a-b-c)
10.因式分解a^2－a－b^2－b＝(a+b)(a-b-1)
11.因式分解(3a－b)2－4(3a－b)(a＋3b)＋4(a＋3b)2＝[3a-b-2(a+3b)]^2=(a-7b)^2
12.因式分解(a＋3)2－6(a＋3)＝(a+3)(a-3)

(1)3x^2－6x＝3x(x-2)
(2)49x^2－25＝(7x+5)(7x-5)
(3)6x^2－13x＋5＝(2x-1)(3x-5)
(4)x^2＋2－3x＝(x-1)(x-2)
(5)12x^2－23x－24＝(3x-8)(4x+3)
(6)(x＋6)(x－6)－(x－6)＝(x-6)(x+5)
(7)3(x＋2)(x－5)－(x＋2)(x－3)＝2(x-6)(x+2)
