For a quadratic equation in standard form:

the discriminant is

First rearrange the given equation into standard form

11x^2-9x -1 =0#

Evaluate the discriminant:

Since the solutions to a quadratic can be evaluated by the formula

It follows that

For this example,

therefore there are 2 Real solutions
