Web24 jan. 2024 · We know \ ( {b^2} – 4ac\) determines whether the quadratic equation \ (a {x^2} + bx + c = 0\) has real roots or not, \ ( {b^2} – 4ac\) is known as the discriminant of these quadratic equations. Therefore, a quadratic equation \ (a {x^2} + bx + c = 0\) has Two distinct real roots, if \ ( {b^2} – 4ac > 0\) WebEvery quadratic equation can have 0, 1 or 2 real solutions derived by the formula: \displaystyle x=\frac {-b \pm \sqrt {b^2 - 4ac}} {2a} x = 2a−b ± b2 −4ac. The number D = b2 - 4ac is called "discriminant". If D < 0, then the quadratic equation has no real solutions (it has 2 complex solutions). If D = 0, then the quadratic equation has 1 ...
