If the discriminant of a quadratic equation is \(D=25\), what will be the nature of its roots?

Answer and explanation

Correct answer: The roots will be real and distinct

For a quadratic equation, the discriminant is \(D=b^2-4ac\). When \(D>0\), the two roots are real and distinct. Since \(D=25>0\), option A is correct. Equal roots occur when \(D=0\), while non-real roots occur when \(D<0\). Exam tip: Check the sign of the discriminant first to determine the nature of the roots.
