WebA complex number is a number that can be written in the form a + bi a+ bi, where a a and b b are real numbers and i i is the imaginary unit defined by i^2 = -1 i2 = −1. The set of complex numbers, denoted by \mathbb {C} C, includes the set of real numbers \left ( \mathbb {R} \right) (R) and the set of pure imaginary numbers.

WebYes, indeed, it is, because zero is a valid number. It's not that the solution is "nothing"; it's that the solution is "something", and that this "something" is zero. So my answer is: x = 0.
