俗话说:没有最难,只有更难.
对下面的式子进行因式分解:
7854634047473965559808000 + 5361415210454476261939200 x +
1679833256559907126106880 x^2 + 321310109473454304853632 x^3 +
42074529611692088667024 x^4 + 4007363862391302729744 x^5 +
287775325467641891880 x^6 + 15930666887371904304 x^7 +
688874416712280513 x^8 + 23421045420371313 x^9 +
626564678067900 x^10 + 13123624010796 x^11 + 212719408902 x^12 +
2613884742 x^13 + 23528340 x^14 + 146268 x^15 + 561 x^16 + x^17
绝对超难,
结果是:
(9 + x) (12 + x) (15 + x) (18 + x) (21 + x) (24 + x) (27 + x) (30 +
x) (33 + x) (36 + x) (39 + x) (42 + x) (45 + x) (48 + x) (51 +
x) (54 + x) (57 + x)
