1. The graphs of a quadratic trinomial with a positive leading coefficient 2 and its derivative intersect at the vertex of the parabola with abscissa $x_{0}$ and at another point with abscissa $x_{1}$. Find the total area of both regions bounded by the graphs of the trinomial, its derivative, and the line symmetric to the line $x=x_{1}$ with respect to the line $x=x_{0}$ (see figure).
