How might the discriminant be used in the analysis of random polynomials?

Let gcd(a, b, c) = 1, D = b 2 - 4ac. Then as remarked in Mathews ([4, pages 132--133]), then there exist integers #, # such that a# 2 + b## + c# 2 = a ... The discriminant of a quadratic is the expression inside the radical of the quadratic formula. b2−4(ac) b 2 - 4 ( a ... Jun 4, 2020 ... I wish I could use b^2-4ac>0 to check whether the people are real or not. Jun 4, 2014 ... 3 Answers 3 ... Δ=b2−4ac>0 means that the equation has two real solutions. Δ=b2−4ac<0 means that the equation has no real solutions, but two ... Proposition 3 d=a+b+c positive integers with b2 >4ac. (i) When a ≡ b ≡ c ... 2+(b−δ)t. 4. ⊕ Z b+δ−2δt+. 4. ⊂ C. 2 . 4/8. 4.

Let ƒ(x,y) = ax2 + bxy + cy2 be an indefinite binary quadratic form, with real coefficients a, b, c, and discriminant d = b2 —4ac. b2 − 4ac = (−5)2 − 4 × 1 × 6=1 therefore, there are two solutions.
