Well, this is a task for those who prepares to enter a university.(adsbygoogle = window.adsbygoogle || []).push({});

According to the textbook this task is among the easiest ones.

I managed to simplify this part of the (4b^4 + 4ab^2+a^2):(2b^2 + a) = 2b^2 + a.

Well, I can't proceed any further.

Could you give me a hint?
