Write the discriminant of quadratic equation:x2 -2x + k = 0, k ∈ R |
Answer» Given equation, x2 – 2x + k = 0 It is in the form of ax2 + bx + c = 0 Where, a = 1, b = -2, and c = k So, the discriminant is given by D = b2 – 4ac D = (-2)2 – 4(1)(k) = 4 – 4k Hence, the discriminant of the given equation is (4 – 4k). |
