How many solutions does j2−9=−13 have?

1 answer

The equation j^2 - 9 = -13 can be rewritten as j^2 = -4.

Since the square of any real number is always non-negative, there are no real solutions to this equation. However, there are imaginary solutions.

Therefore, the equation j^2 - 9 = -13 has 2 imaginary solutions.
