几题因式分解求过程、、3种混合 (1)ax+ay+a (2)3mx-6mx²(3)4a²-10ah4.x²y+xy²
(1)ax+ay+a (2)3mx-6mx²(3)4a²-10ah(4).x²y+xy²(5)12xyz-9x²y² (6)x²-6xy+x (7)-25x+x³ (8)4x³-8x²+4x (9) m²-n²+2m-2n
答
(1)ax+ay+a =a(x+y+1)(2)3mx-6mx²=3mx(1-2x)(3)4a²-10ah=2a(2a-5h)(4).x²y+xy²=xy(x+y)(5)12xyz-9x²y²=3xy(4z-3xy)(6)x²-6xy+x =x(x-6y+1) (7)-25x+x³ =-x(5...
