Answer
Step-by-step solution
4 stepsConsider the general form of the equation .
This equation can be rearranged to solve for :
If the constant is a positive odd number (like 1, 3, 5, etc.), let's use as an example.
To find , we take the square root of both sides.
We know that (the imaginary unit).
So, we can rewrite the expression:
These solutions are complex numbers.
The parity (odd or even) of a positive constant in an equation of the form does not change the nature of the solutions. As long as is positive, will be negative, and taking the square root of a negative number will always result in complex numbers.
The solutions will still be complex numbers.
