What is the correct conclusion about the nature of the roots of the quadratic equation \(8x^2-4x+3=0\)?

Answer and explanation

Correct answer: No real roots; \(D=-80\)

Here, \(a=8\), \(b=-4\), and \(c=3\). Thus, the discriminant is \(D=b^2-4ac=(-4)^2-4(8)(3)=16-96=-80\). Since \(D<0\), the equation has no real roots; its roots are complex. Exam tip: A negative discriminant immediately indicates that a quadratic equation has no real roots.
