WebApr 15, 2024 · If the discriminant is positive and is a perfect square (ex. #36, 121, 100, 625#), the roots are rational. If the discriminant is positive and is not a perfect square (ex. #84, 52, 700#), the roots are irrational. A positive discriminant has two real roots (these real roots can be irrational or rational). Web1. Let a, b, c be the rational roots. Then we have. a + b + c = 2, a b + b c + c a = − 2, m = − a b c. Replace c = 2 − a − b , a 2 + b 2 + a b − 2 ( a + b) − 2 = 0.
