Therefore the square roots are 2 and -2

Why is the number i imaginary?

i is equalled to the square root of -1. The square root is a number which, multiplied by itself, will give a number (eg: 2 is the square root of 4 because 2x2=4) But negative numbers can't have square roots because any number multiplied by itself will be positive. So 'i' is imaginary. You use 'i' in calculus to figure out complex problems.
