Write the discriminant of quadratic equation:(x – 1)(2x – 1) = 0 |
Answer» Given equation, (x -1) (2x -1) = 0 On expanding it, we get 2x2 – 3x + 1 = 0 It is in the form of ax2 + bx + c = 0 Where, a = 2, b = -3, c = 1 So, the discriminant is given by D = b2 – 4ac D = (-3)2 – 4 x 2 x 1 D = 9 – 8 = 1 Hence, the discriminant of the given quadratic equation is 1. |
