因式分解:(1)a5-a (2)xy2-2xy+xxiexiele
因式分解:(1)a5-a (2)xy2-2xy+x
xiexiele
因式分解:(1)a5-a (2)xy2-2xy+xxiexiele
(1)a^5-a
=a(a^4-1)
=a(a^2+1)(a^2-1)
=a(a^2+1)(a+1)(a-1)
(2)xy2-2xy+x
=x(y^2-2y+1)
=x(y-1)^2
1. a(a^2+1)(a+1)(a-1)
2. x(y-1)^2
1、a(a+1)(a-1)(a2+1)
2、x(y-1)(y-1)
a5-a
=a(a4-1)=a(a2+1)(a+1)(a-1)
xy2-2xy+x
=x(y2-2y+1)
=x(y-1)2
因式分解:(1)a5-a (2)xy2-2xy+xxiexiele
因式分解:x3-2x2y+xy2
x3+2x2+xy2因式分解
xy2-2xy-3x-y2-2y-1因式分解.
a5+a+1 还有很多因式分解
x3+2x2y+2xy2+y3因式分解
因式分解x3-xy2x3-xy2
计算:3xy(x2y-xy2+xy)-xy2(2x2-3xy+2x)因式分解
计算题:(-1/3xy2)[xy(2x-y)+xy2],
因式分解:x3-y3-x2y+xy2
因式分解x3+x2+xy-xy2
(xy2)2÷(xy2)3
因式分解:a2-a4-2a5-a6
因式分解:a2-a4+2a5-a6
已知A=x3+2y3-xy2,B=﹣y3+x3+2xy2,其中x=3分之1,y=2.求a-b的值
化简-x2-3x+2x2+4x.xy2-2/3x2y-xy2/2+2x2y.2a-1/2ab-(a2-ab)
两个因式分解的题目,(其中x2是x的二次方的意思),(1)a-a5(2)1-6ab3+9(a2)(b6)
因式分解(a+b+c)5-a5-b5-c5.急用!
