A complex number is a number of the form a+bi, 

if b=0, that is if the number is a, then it is a Real number

if a=0, that is if the number is bi, then it is called an imaginary number.



All imaginary numbers are complex numbers.

Also, all real numbers (non-imaginary) are complex numbers.


Thus, all the numbers given are complex.

3i   :   imaginary

-5i :    imaginary

6-i:    complex

square root of 21: real, non-imaginary, complex

Negative square root of 16=-4:  real, non-imaginary, complex

<span>Square root of -14 = (square root of 14)i:   imaginary</span>

Hello DestinyKiara99 o/
We can solve this equation using the quadratic formula
Check it out...

x² + 6x - 24 = 0       

Δ = 6² - 4.1.(-24)
Δ = 36 + 96
Δ = 132

x = -6 +/- √132    x' = -3 + √33
