Factor completely. 0^2 + 9 Select the correct choice below and fill in any answer boxes within your choice. The answer is The expression is prime.

c² + 9 can be written as c² + 0*c + 9

So here a=1, b=0 and c=9.

So a*c = 1*9=9 and b =0

We have to find two numbers whose product is 9 and whose sum is 0.

since we can\'t find two such numbers, it means that we cannot factorize it.

So the given expression is prime.
