How many real number solutions does the equation have? 4x^2-5x+9=0
The discriminant of the quadratic equation is:
b^2 - 4ac = (-5)^2 - 4(4)(9) = -119
Since the discriminant is negative, the quadratic equation has no real number solutions.
b^2 - 4ac = (-5)^2 - 4(4)(9) = -119
Since the discriminant is negative, the quadratic equation has no real number solutions.
