Since this is a quadratic equation in the form ax^2 + bx + c = 0, we can use the discriminant to determine the number of real number solutions.

The discriminant is given by b^2 - 4ac. In this case, a = 1, b = 0, and c = -1.

So the discriminant = 0^2 - 4*1*(-1) = 4.

Since the discriminant is positive (4 > 0), the quadratic equation has two distinct real number solutions.
