Imaginary roots appear in a quadratic equation when the discriminant of the quadratic equation, the part under the square root sign (b² – 4ac), is negative. If this value is negative, you can't actually take the square root, and the answers are not real.

An imaginary number is a number that, when squared, has a negative result. Essentially, an imaginary number is the square root of a negative number and does not have a tangible value.

# data[].attributes.body
imaginary numbers are defined as the square root of the negative numbers where it does not have a definite value

Imaginary numbers are the numbers when squared it gives the negative result.
