There is one and only one real solution, and no imaginary solutions, of the equation x13 = 1.
The solution is x = 1.
If x = -1 then x13 = -1, so that does not work.
If x = i, then x13 = -i, so that does not work.
If x = -i, then x13 = -i, so that does not work.
discriminant
imaginary
As many solutions as there are points in the domain.
Is a trigonometric equation which has infinitely many real solutions.
One solution: x = -4
It has two equal solutions for x which are x = 2 and x = 2
If the highest degree of an equation is 3, then the equation must have 3 solutions. Solutions can be: 1) 3 real solutions 2) one real and two imaginary solutions.

discriminant
imaginary
The quadratic equation will have two solutions.
As many solutions as there are points in the domain.
It has infinitely many solutions.
0 real solutions. There are other solutions in the complex planes (with i, the imaginary number), but there are no real solutions.
0 = 0 is an identity and not an equation. Equations have solutions, identities do not.
Is a trigonometric equation which has infinitely many real solutions.
