Can the discriminant be used to study the behavior of singularities of solutions to nonlinear partial differential equations?

1. Let ƒ(x,y) = ax2 + bxy + cy2 be an indefinite binary quadratic form, with real coefficients a, b, c, and discriminant d = b2 —4ac. b = (2siso + ses) (Ved – Ves). c = ses (ses + siso) (Ves – Ved). Taking into account that smax > siso the answer of the sum is. x = {-b - √ (b2 – 4ac)} / 2a. ) Suppose that a ~ 0 and that b2 — 4ac ≥ 0.
