因式分解:25(x-y)²+10(y-x)+1
因式分解:25(x-y)²+10(y-x)+1
25(x-y)²-10(y-z)+1因式分解
因式分解:25(x+y)²-9(x-y)²;(x+y)²-4(x+y-1).
25(x-y)的平方+10(y-x)+1因式分解
因式分解:x²(x-y)+(y-x)
因式分解(x²-y)²-(1-y)²
(2x-y)²-10(2x-y)+25 因式分解 过程啊,步骤啊.
(x+y)²+x+y-6因式分解
(x-y)²-(x-y)因式分解
因式分解 a²(y-x)+(x-y)
因式分解 (1).(x+y)(x+y-6)+9 (2).x²-16y²-x-4y
因式分解(x+y)²(x-y)-(x+y)(x²+y²)
