Answer:
4a^2(4a^2+b^2)+b^4
Explanation:
factorize 16a4+4a2b2+b4
The correct expression is 16a^4+4a^2b^2+b^4
Given data
We have the following expression
16a^4+4a^2b^2+b^4
Let us group the terms
(16a^4+4a^2b^2)+b^4
Let us factor out all the common terms in the expression
we have
4a^2(4a^2+b^2)+b^4
Hence the final expression is 4a^2(4a^2+b^2)+b^4
