It can't be factorized over , but it can be factorized over :

R is the set of numbers you encounter in everyday life. This includes whole numbers, fractions and numbers like Pi. C is the set of all those and the complex numbers, which includes i, the root of -1.
Fantastic. What does C and R stand for, if they stand for anything?
C stands for Complex, R for Real. (I think)
