Choose the correct option regarding the nature of the roots of the quadratic equation \(5x^2-6x+2=0\).

Answer and explanation

Correct answer: No real roots \(D=-4\)

Here, \(a=5\), \(b=-6\), and \(c=2\). The discriminant is \(D=b^2-4ac=(-6)^2-4(5)(2)=36-40=-4\). Since \(D<0\), the equation has no real roots. Equal real roots occur only when \(D=0\), so option B is incorrect; the other listed discriminant values are also miscalculations. Exam tip: determine the nature of quadratic roots by checking the sign of the discriminant first.
