分解因式4x的2次方+4xy+y的2次方-10x-5y+6
举一反三
- 分解因式()x()3()y()-()2()x()2()y()2()+()xy()3()正确的是A.()xy()(()x()+()y())()2()B.()xy()(()x()2()﹣()2()xy()+()y()2())()C.()xy()(()x()2()+2()xy()﹣()y()2())()D.()xy()(()x()﹣()y())()2
- 1.(3m-2n)三次方+(3m+2n)三次方2.x六次方（x方-y方）+y六次方（y方-x方）3.8（x+y）3+1
- 若(2·X的平方+X+1)的三次方=AⅠ·X的6次方+AⅡ·X的5次方+AⅢ·X的4次方+AⅣ·X的3次方+AⅤ·X的2次方+AⅥ·X+AⅦ
- 已知x²+xy=5,xy+y²=-4,求（1）x²-y²的值；（2）4x²+xy-3y²的值
- x-y=1,x立方-y立方=2,求x四次方+y四次方,x五次方-y五次方
