因式分解﹙x-y-z﹚²-﹙x+y+z﹚²因式分解﹙x-y-z﹚²-﹙x+y+z﹚²因式分解﹙x-y-z﹚²-﹙x+y+z﹚²﹙x-y-z﹚

因式分解﹙x-y-z﹚²-﹙x+y+z﹚²
因式分解﹙x-y-z﹚²-﹙x+y+z﹚²

因式分解﹙x-y-z﹚²-﹙x+y+z﹚²
﹙x-y-z﹚²-﹙x+y+z﹚²
=[﹙x-y-z﹚+﹙x+y+z﹚][﹙x-y-z﹚-﹙x+y+z﹚]
=2x(-2y-2z)
=-4x(y+z)

原式=(x-y-z+x+y+z)(x-y-z-x-y-z)
=2x(-2y-2z)
=-4x(y+z)

原式=(x-y-z+x+y+z)(x-y-z-x-y-z)
=2x(-2y-2z)
=-4x(y+z)


根据公式:
a²-b²=(a-b)(a+b)

原式=
(x-y-z-x-y-z)(x-y-z+x+y+z)
=(-2y-2z)(2x)
= -4x(y+z)

您好:

﹙x-y-z﹚²-﹙x+y+z﹚²
=(x-y-z+x+y+z)(x-y-x-y-z)
=2x(-2y-2z)
=-4x(y+z)
