you are entering the realm of complex numbers
i = √-1
That is, i^2 = -1
√-196 = √(196 * -1) = √196 * √-1 = 14i
better start reading on the topic.
What is √−196?
I am super confused. Please help.

Ok, Thank you soooo much!
√−196 is not defined as a real number, rather it is imaginary. We can define √−196 as the product of √196 and √−1. Since √−1=i, then √−196=±14i.
Not quite, AJ+L
√196 is 14
not ±14
It happens that (-14)^2 = 196, but the square root is defined as the positive number
