In the quadratic equation kx2-6x-1 0
WebTamang sagot sa tanong: determine the discriminant and nature of roots of each quadratic equation. a. x2-6x+9=0 b. x2-4x+3=0 c. x2-7x-4=0 d.2x2+3x+5=0 Weblet α be the one root of the quadratic equation. So, the other root will be 1 α. We know that for the quadratic equation a x 2 + b x + c product of the roots is given by c a. Thus, the product of the roots of given quadratic equation = k 2. ⇒ α × 1 α = k 2 ⇒ 2 = k ⇒ k = 2. Hence, the value of k is 2.
