解:(1)4x2y2+12x3y5-8x4y3=4x2y2(1+3xy3-2x2y);
(2)(x+y)2-4y2
=(x+y+2y)(x+y-2y)
=(x+3y)(x-y);
(3)a3-10a2+25a
=a(a2-10a+25)
=a(a+5)2;
(4)-x5y3+x3y5
=-x3y3(x2-y2)
=-x3y3(x+y)(x-y).解析分析:(1)提取公因式4x2y2,即可求得
(2)(x+y)2-4y2
=(x+y+2y)(x+y-2y)
=(x+3y)(x-y);
(3)a3-10a2+25a
=a(a2-10a+25)
=a(a+5)2;
(4)-x5y3+x3y5
=-x3y3(x2-y2)
=-x3y3(x+y)(x-y).解析分析:(1)提取公因式4x2y2,即可求得
