My friend and I are arguing again, about Maths (How cool are we?).
Please, just assure me (and him), that you cannot factorise the equation:
So that there are two brackets, each with a value of in.

(x+10)(x+10) - 20x

What is factorising over "C"?
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)

N - natural numbers
Z - integers
Q - rational numbers
R - real numbers
C - complex numbers
Its important to know what each set includes and its properties.
