Answer 2

Answer:

$Factors \:of \:a^{2}+8a+16\\=(a+4)(a+4)$

Step-by-step explanation:

$Given\: expression ,a^{2}+8a+16$

$=a^{2}+2\times a \times 4+4^{2}\\=\left(a+4\right)^{2}$

/* By algebraic identity:

$\boxed { x^{2}+2xy+y^{2}=(x+y)^{2}}$

$=(a+4)(a+4)$

Therefore,

$Factors \:of \:a^{2}+8a+16\\=(a+4)(a+4)$
