Complex Numbers to Solve EquationsBy making use of the imaginary number i we can solve equations that involve the square roots of negative numbers. Complex numbers enable us to solve equations that we wouldn't be able to otherwise solve. Examine the following example:
Without the ability to take the square root of a negative number we would not be able to solve these kinds of problems.
