April 8 Monday Fine

Recently we had a class meeting on the topic of My Chinese Dream. Inspired by President Xi’s Chinese Dream, everyone talked enthusiastically about his understanding of the Chinese Dream. We all believe that this dream will come true in the future. I also talked about my own dream. I have always wanted to be a doctor. Not only can doctors save people’s lives but also they are doing a respectable job. Doctors can also help people to live a better life with their professional knowledge .To realize my dream, I must try to work hard from now on. I must learn as much as I can so that I can get into a good medical college, where I can prepare myself adequately for the job of a doctor. Only in this way can I accomplish my goal.

设a,b,c分别是△ABC的三个角A,B,C所对的边,研究A=2B是a2=b(b+c)的什么条件?以下是某同学的解法:
由A=2B,得sinA=sin2B,即:sinA=2sinB•cosB⇒a=2bcosB
⇒a=2b•
a2+c2-b2
2ac
.变形得a2c=a2b+bc2-b3⇒a2(c-b)
=b(b+c)(c-b)
所以,b=c或a2=b(b+c)
由此可知:A=2B是a2=b(b+c)的必要非充分条件.
请你研究这位同学解法的正误,并结合自己的思考,可以得到“A=2B”是“a2=b(b+c)”的(  )条件.
A.充分非必要B.必要非充分
C.充要D.非充分非必要
