The number of real roots of the equation
SpletIn the first diagram, we can see that this parabola has two roots. The second diagram has one root and the third diagram has no roots. The discriminant can be used in the … SpletFrom the quadratic formula, x = -b/2a +/- (sqrt (bb-4ac))/2a If 1 root is non-real, then the discriminant is negative, and both roots have an imaginary component; in one root it's added to -b/2a, in the other subtracted. So there must be 2 non-real roots. If 1 root is real, …
