For real and equal roots
WebAccording to the nature of roots of a quadratic equation if the discriminant D = 0, then the quadratic equation has real and equal roots. By nature of roots of equation D = 0 ⇒ 4 - 4 k + 1 = 0 ⇒ - 4 k = - 1 ⇒ k = 1 4 Hence, for k = 1 4 the equation k 2 x 2 - 2 2 k - 1 x + 4 = 0 has equal roots.
