Well for the problem

x2 + 1 = 0

 

subtract 1 from both sides

x= -1

 

square root both sides

x = ±√(-1)

 

so x = ±i

or x = 0 + 1i    or     x = 0 - 1i

 

As for the magnitude, I don't really know but I googled it and found some place that said when a complex number is written like this: " a + bi ", the magnitude is √(a+ b2).

So if that's right then the magnitude for this would be √(02 + 12) = 1
