How many and what type of solutions does the quadratic equation x^2+81=0 have?

two real solutions
two imaginary solutions
one real solution
one imaginary solution

For this case we have the following quadratic equation:

We look for the solutions:

We subtract 81 from both sides of the equation:

We apply square root on both sides to eliminate the exponent:

We have to:

So:
