初二数学乘法公式与因式分解...……*&&¥%@@&@%#%@&*&%¥#@#……&之类的题,
比如(聚几个经典点的题型):
计算题!
(M^3+5N)(5N-M^3)
(2A+B)^2-(B-2A)^2
=
=
=
(3A-2B)(3A+2B)(9A^2+4B^2)
=
=
=
(2M+N)^2(2M-N)^2
=
=
=
(X-Y+Z)^2
=
=
=
分解因式:
-2a^3+12a^2-18a
=
=
=
m^4-16n^4
=
=
=
(X+Y)^2-4(X+Y-1)
=
=
=
4A^2B^2-(A^2+B^2)^2
=
=
=
等等,如果有其它类型也要,只要是解题思路稍有不一样的就要
