What is a number that can be written in the form a plus bi where a and b are real numbers?
A number of the form (a + bi) is a complex number.
The set of complex numbers contains only numbers of the form a plus bi where a and b are positive numbers and you is the imaginary unit?
Not exactly. The numbers (a & b) can be any real number (positive or negative). It is the letter i, which represents the imaginary unit sqrt(-1).False

That expression can't actually be factored without using complex numbers. If you want to use complex numbers, then it would come out as a "difference of squares":(x + i)(x - i)

Can x2 plus 1 be factored twice?
x2 + 1 can't be factored in the real numbers. If complex numbers are acceptable, it can be factored as (x + i)(x - i).
