Question 258819
I need help factoring this problem completely:
<pre><font size = 4 color = "indigo"><b>
{{{16a^2 + 25}}}
<pre><font size = 4 color = "indigo"><b>
That cannot be factored (using integers).

If that had been a minus sign between them we could
have factored it, but the sum of two squares cannot
be factored (using integers).
