$\left(x^{4}+4x^2+4\right)\left(x^4+4\right)^4$
Learn how to solve problems step by step online. Expand the expression (x^2+2)^2(x^4+4)^4. Expand \left(x^2+2\right)^2. Expand the binomial \left(x^4+4\right)^4. We can multiply the polynomials \left(x^{4}+4x^2+4\right)\left(x^{16}+16x^{12}+96x^{8}+256x^4+256\right) by using the FOIL method. The acronym F O I L stands for multiplying the terms in each bracket in the following order: First by First (F\times F), Outer by Outer (O\times O), Inner by Inner (I\times I), Last by Last (L\times L). Then, combine the four terms in a sum.
