Its type depends on discriminant $\Delta = B^2 - 4AC$:
$$ u_tt = c^2 u_xx $$ D’Alembert’s solution: $$ u(x,t) = \frac12[f(x+ct) + f(x-ct)] + \frac12c \int_x-ct^x+ct g(s) ds $$

Here $P=1, Q=1, R=1$. Auxiliary equations: $\fracdx1 = \fracdy1 = \fracdz1$ From $dx = dy$ → $x - y = c_1$ From $dx = dz$ → $x - z = c_2$ General solution: $F(x-y, x-z) = 0$ or $x - z = f(x-y)$. Its type depends on discriminant $\Delta = B^2
