If the discriminant \\(b^2-4ac=9\\) of a quadratic equation is 9, what will be the nature of its roots?

Answer and explanation

Correct answer: Real and distinct

For a quadratic equation, the discriminant is \\(D=b^2-4ac\\). Here, \\(D=9>0\\), so the two roots are real and distinct. Equal real roots require \\(D=0\\), so option B is incorrect. Exam tip: \\(D>0\\) indicates real and distinct roots.
