Final answer:
The discriminant of the quadratic equation x^2 - 6x + 10 = 0 is -4, indicating that the equation has two imaginary solutions.
Step-by-step explanation:
To find the discriminant of the quadratic equation x^2 - 6x + 10 = 0 and determine the number and type of solutions it has, we can use the discriminant formula D = b^2 - 4ac, where a, b, and c are coefficients of the quadratic equation ax^2 + bx + c = 0. In this equation, a = 1, b = -6, and c = 10. Plugging these values into the discriminant formula, we get:
D = (-6)^2 - 4(1)(10)
D = 36 - 40
D = -4
Since the discriminant is negative (D = -4), it indicates that this quadratic equation has two imaginary solutions. This corresponds to option d.
