Write the discriminant of quadratic equation:x2 + 2x + 4 = 0 |
Answer» Given equation, x2 + 2x + 4 = 0 It is in the form of ax2 + bx + c = 0 Where, a = 1, b = 2 and c = 4 So, the discriminant is given by D = b2 – 4ac D = (2)2 – 4 x 1 x 4 D = 4 – 16 = – 12 Hence, the discriminant of the given quadratic equation is – 12. |
