Probability quadratic has real roots
WebbGiven,the quadratice equation does not change even the roots are squared. Let the roots of the quadratic equation be p,q. After squaring, the new roots are p 2,q 2. Since the quadratic equation does not change,sum of the roots,product of the roots for new equation is equal to the previous equation values. Product of the roots, pq=(pq) 2 ⇒pq(pq−1)=0 WebbThere are really two distinct cases when a quadratic has real roots: The first case is when the discriminant is positive (b2 – 4ac > 0) – this gives us two distinct real roots. The …
