9+24(x-y)+16(x-y)=?分解因式16(x-y)右上角有个²9+24(x-y)+16(x-y)=?分解因式16(x-y)右上角有个²9+24(x-y)+16(x-y)=
9+24(x-y)+16(x-y)=?分解因式 16(x-y)右上角有个²
9+24(x-y)+16(x-y)=?分解因式
16(x-y)右上角有个²
9+24(x-y)+16(x-y)=?分解因式 16(x-y)右上角有个²
原式=[4(x-y)]^2+2*4(x-y)*3+3^2
=[4(x-y)+3]^2
=(4x-4y+3)^2
40(x-y)+9
应该是9+24(x-y)+16(x-y)²
原式=[3+4(x-y)]²
=(4x-4y+3)²
少了个平方吧
已知x^2+xy=16 y^2+xy=9 求(x+y) (x-y)分别是 x+y x-y 不是乘
9(x-y)^2+42(x-y)+49 16(x+y)2+40(x+y)(x-y)+25(x-y)^2 你懂的……没分了= =谅解..
80分 [(x-y)²]³×(x-y)=
一 4(x-y-1)=3(1-y)-2 {x/2+y/3=2 二 2(x-y)-x-y/4=-1{ 6(x+y)-4(2x-y)=16好的可以追加分~
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
X*X-5XY+6Y*Y=0,X/Y=?用因式分解法.
16(x+y)`-24(x+y)+9 `表示平方 因式分解
分解因式:16(x+y)^2-24(x+y)+9
16-24(x-y)+9(x-y)^2kuai
16-24(x+y)+9(x+y)的平方
16+24(x+y)+9(x+y)^2
16(x+y)^2-24(x+y)+9
化简 x / y(x+y) - y / x(x+y) =
