用因式分解计算2^12-2^11-2^10-2^9-2^8-2^7-2^6+3
2^12-2^11-2^10-2^9-2^8-2^7-2^6+3
=2^11(2-1)-2^10-2^9-2^8-2^7-2^6+3
=2^11-2^10-2^9-2^8-2^7-2^6+3
=2^10(2-1)-2^9-2^8-2^7-2^6+3
=2^10-2^9-2^8-2^7-2^6+3
=2^9(2-1)-2^8-2^7-2^6+3
=2^9-2^8-2^7-2^6+3
=2^8(2-1)-2^7-2^6+3
=2^8-2^7-2^6+3
=2^7(2-1)-2^6+3
=2^7-2^6+3
=2^6(2-1)+3
=2^6+3
=64+3
=67
