Homework Statement
x2+16
Homework Equations
?
The Attempt at a Solution
If you attempt to solve it with (x+4)(x+4), it results in x2+8x+16, which is not equivalent. I believe it may be prime. I am looking for the formula (if there is any) to explain this. Allow me to give an example:
a2+2ab+b2 <<< This is the square of a binomial formula. Does my type of problem have a formula that explains its nature? If it's prime, how would I phrase it? axn+b=?
edit: back of the book states it is prime. Oops :p
