感谢 但是这题是选择题 你的第2种答案( y - x )( y - x - 1 )符合d选项再次感谢
(x-y)^2-(y-x)的因式分解的结果是
( x - y )" - ( y - x )= ( x - y )" + ( x - y )= ( x - y )[ ( x - y ) + 1 ]= ( x - y )( x - y + 1 )或者 = ( y - x )" - ( y - x )= ( y - x )[ ( y - x ) - 1 ]= ( y - x )( y - x - 1 )...
(x-y)2-(y-x)因式分解的结果是( )A.(y-x)(x-y)B.(x-y)(x-y-1)C.(y...
根据题意得:(x-y)2-(y-x)=(y-x)2-(y-x)=(y-x)(y-x-1).故答案为C.
(x-y)^2-(y-x) 因式分解
(x-y)^2-(y-x)=﹙x-y﹚²+﹙x-y﹚=﹙x-y﹚﹙x-y+1﹚
(x-y)^2-x+y因式分解
原式=(x-y)^2-(x-y)=(x-y)(x-y-1)
(x-y)²+y(y-x)因式分解?
因式分解 (x-y)²+y(y-x)=(x-y)²-y(x-y)=(x-y-y)(x-y)=(x-2y)(x-y)
x(x-y)的二次方-2(y-x)的三次方求因式分解
x(x-y)²-2(y-x)³=x(x-y)²+2(x-y)³=(x-y)²[x+2(x-y)=(x-y)²(x+2x-2y)=(x-y)²(3x-2y)
x(x-y)^2-xy(y-x)^2 因式分解
您好:x(x-y)^2-xy(y-x)^2 =x(x-y)^2-xy(x-y)^2 =x(x-y)²(1-y)如果本题有什么不明白可以追问,如果满意请点击“选为满意答案”如果有其他问题请采纳本题后另发点击向我求助,答题不易,请谅解,谢谢。祝学习进步!
因式分解:x(x-y)的平方-y(x-y)怎么做
x(x-y)的平方-y(x-y)=(x-y)[x(x-y)-y]=(x-y)(x²-xy-y)
x的平方(x-y)+y的平方(y-x)因式分解
x的平方(x-y)+y的平方(y-x)=x的平方(x-y)-y的平方(x-y)=(x-y)(x的平方-y的平方)=(x-y)(x+y)(x-y)=(x-y)的平方(x+y)
(y-x)平方-2(x-y)因式分解
原式=(x-y)^2-2(x-y).提取公因式(x-y).得(x-y)(x-y-2)。我是金山的老师,有问题再沟通
