简便计算:(x-2)²(x+2)²(x²-4)²
简便计算:(x-2)²(x+2)²(x²-4)²
简便计算:(x-2)²(x+2)²(x²-4)²
简便计算:
(x-2)²(x+2)²(x²-4)²
解,得:
==(x-2)²(x+2)²(x²-4)(x²-4)
==(x-2)²(x+2)(x+2)(x-2)(x+2)(x-2)
==(x-2)(x-2)(x+2)(x+2)(x+2)(x-2)(x+2)(x-2)
==(x-2)^4(x+2)^4
(x-2)²(x+2)²(x²-4)²
=(x-2)(x+2)(x-2)(x+2)(x²-4)²
=(x²-4)²(x²-4)²
=(x²-4)^4
=x^8-16x^6+64x^4+256x^2+1024我好像感觉您算错了,能再算一遍吗?谢谢。最后一步
全部展开
(x-2)²(x+2)²(x²-4)²
=(x-2)(x+2)(x-2)(x+2)(x²-4)²
=(x²-4)²(x²-4)²
=(x²-4)^4
=x^8-16x^6+64x^4+256x^2+1024
