What is the nature of the roots of the quadratic equation \(4x^2+4x+5=0\)?

Answer and explanation

Correct answer: no real roots

Here, \(a=4\), \(b=4\), and \(c=5\). The discriminant is \(D=b^2-4ac=4^2-4(4)(5)=16-80=-64<0\). Hence, the equation has no real roots; its roots are complex. Exam tip: For a quadratic equation, \(D<0\) indicates no real roots.
