The discriminant of a quadratic equation is calculated through the equation,
D = b² - 4ac
where a and b are the numerical coefficients of x² and x, respectively, and c is the constant. Substituting the values,
D = (-17)² - (4)(3)(10)
= 169
Since the discriminant is greater than zero and is a perfect square, the roots are two rational solutions. Thus, the answer is letter C.
