因式分解.(1)6a²b³(x-y)-9a³b²(x-y)³ (2)x的8次方-1(3)2x²-7xy+6y²
因式分解.(1)6a²b³(x-y)-9a³b²(x-y)³ (2)x的8次方-1
(3)2x²-7xy+6y²

因式分解.(1)6a²b³(x-y)-9a³b²(x-y)³ (2)x的8次方-1(3)2x²-7xy+6y²
(1)6a²b³(x-y)-9a³b²(x-y)³
=3a²b²(x-y)[2b-3a(x-y)²]
=3a²b²(x-y)(2b-3ax²+6axy-3ay²)
(2)x的8次方-1
=(x^4+1)(x^4-1)
=(x^4+1)(x²+1)(x²-1)
=(x^4+1)(x²+1)(x+1)(x-1)
(3)2x²-7xy+6y²
=(2x-3y)(x-2y)

=(x^4+1)(x...

全部展开

(1)6a²b³(x-y)-9a³b²(x-y)³
=3a²b²(x-y)[2b-3a(x-y)²]
=3a²b²(x-y)(2b-3ax²+6axy-3ay²)
(2)x的8次方-1
=(x^4+1)(x^4-1)
=(x^4+1)(x²+1)(x²-2)
=(x^4+1)(x²+1)(x+1)(x-1)
(3)2x²-7xy+6y²=(x-2y)(2x-3y)

收起

1.3a^2b^2(x-y)(2b-3a(x-y)^2)
2.没看懂如果是X^8-1的话就是(x+1)(x-1)(x^2+1)(x^4+1)
3.(2x-3y)(x-2y)

1. =3a^2*b^2*(x-y)*(2b-3a(x-y)^3)
2. =(x-1)*(x+1)*(x^4+x^2+1)
3. =(2x-3y)*(x-2y)
