A quadratic equation of the form 0=ax2+bx+c has a discriminant value of -16. How many real number solutions does the equation have?

For a quadratic equation, the discriminant is b² − 4ac. If the discriminant is negative, the quadratic formula requires taking the square root of a negative number, so there are no real solutions. Since the discriminant is −16, the equation has 0 real number solutions, choice B.
