因式分解:(1)3ax^2-a^2x+10ax (2)13(x-1)^2-26(x-1) (3)12x(x-y)^2-8(x-y)^3=4(x-y)^2_____
因式分解:(1)3ax^2-a^2x+10ax (2)13(x-1)^2-26(x-1) (3)12x(x-y)^2-8(x-y)^3=4(x-y)^2_____

因式分解:(1)3ax^2-a^2x+10ax (2)13(x-1)^2-26(x-1) (3)12x(x-y)^2-8(x-y)^3=4(x-y)^2_____
(1)3ax²-a²x+10ax＝ax﹙3x－a＋10﹚;
(2)13(x-1)²-26(x-1)＝13﹙x－1﹚﹙x－1－2﹚＝13﹙x－1﹚﹙x－3﹚;
(3)12x(x-y)²-8(x-y)³=4(x-y)²﹙x＋2y﹚.

(1)3ax^2-a^2x 10ax=ax(3x-a 10) (2)13(x-1)^2-26(x-1)
=13(x-1)*(x-1-2)=13(x-1)(x-3)
(3)12x(x-y)^2-8(x-y)^3
=4(x-y)^2*(x 2y)
