Question 911760
You are stuck at this:  {{{0=u(u^2+14u+32)}}}   and want to go further in factorization.


Now you are looking for two numbers so that their product is 32 and their sum is 14.  Here is a list of combinations to check:


2 & 16;
4 & 8;
Those are all the integer combinations for that.  Notice, 32=2*2*2*2*2.


Neither of those combinations work.  Your factorization is finished.
