WebJul 14, 2024 · How do you prove distinct roots? Since, the discriminant of the given quadratic equation is positive thus it yields real solutions only. As discriminant is non-zero, so roots are distinct. Therefore, for any real value of p the equation x2+px−1=0 has real and distinct roots. WebIf D > 0, all the three roots are real and distinct. If D = 0, then all the three roots are real where at least two of them are equal to each other. If D < 0, then two of its roots are complex numbers and the third root is real. We can see the applications of the discriminant formulas in the following section. Examples Using Discriminant Formulas
