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

Answer and explanation

Correct answer: Real and equal

Here, \(a=2\), \(b=4\), and \(c=2\). The discriminant is \(D=b^2-4ac=4^2-4(2)(2)=16-16=0\). When \(D=0\), the roots are real and equal; in fact, both roots are \(-1\). Therefore, option A is correct. Exam tip: remember that \(D=0\) indicates real and equal roots.
