What is the nature of the roots of the equation \(5x^2-14x+11=0\)?

Answer and explanation

Correct answer: No real roots \(D=-24\)

Here, \(a=5, b=-14, c=11\). Therefore, the discriminant is \(D=b^2-4ac=(-14)^2-4(5)(11)=196-220=-24\). Since \(D<0\), the equation has no real roots. Option D results from a sign error that gives \(D=24\). Exam tip: \(D<0\) means no real roots, \(D=0\) means equal real roots, and \(D>0\) means distinct real roots.
