马上!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
快!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
谢谢啦!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
thank you very much!!!!!!!!!!!!!!!!!!!!!!!!!!!

(a+2b)*2(-a+2b)*2
＝(4b^2-a^2)^2
=16b^4-8a^2b^2+a^4

*好像不对吧，应该是^平方才对。

=(2a+4b)(4b-2a)
=16b*b-4a*a

(2b)^2-(a)^2

*2代表平方么？如果是的话，

（a+2b)^2(-a+2b)^2
=[（a+2b）（-a+2b）]^2
=(4b^2-a^2)^2

^2代表平方

a*a+3b*b≥2b(a+b) 证明：[2a]+[2b]≥[a]+[a+b]+[b] 因式分解：a×a-4b×b-2a+4b 化简 a+2b=a-b 已知5|2a+1|=-4(b-3)*(b-3),a*a*a*a*a*a+b*b=? -25+(a-b)^2 3(a+b)^2[2(-a-b)^3]+[2(a+b)]^3(-a-b)^2 (2a-b)(-2a+b)(2a+b)(-2a-b)=? 5(a+b)(a-b)-2(a+b)*2-3(a-b)*2 (a+b)(a-2b)-(2a-b)(-2a-b)化简后等于多少？

(a+2b)*2(-a+2b)*2=?

(a+2b)2(-a+2b)2=?
