Choose the correct conclusion about the nature of the roots of \(x^2+10x+29=0\).

Answer and explanation

Correct answer: No real roots; \(D=-16\)

Here, \(a=1, b=10, c=29\). Therefore, the discriminant is \(D=b^2-4ac=10^2-4(1)(29)=100-116=-16\). Since \(D<0\), the equation has no real roots. Option B is incorrect because equal real roots require \(D=0\). Exam tip: To determine the nature of roots, first calculate the discriminant and check its sign.
