/**
 * Evaluates and returns the result of evaluating the given implicit function
 * (a degree 2 bivariate polynomial in `x` and `y`) at the point `[x,y]`.
 *
 * * the implicit form is given by: `vₓₓx² +vₓᵧxy + vᵧᵧy² + vₓx + vᵧy + v`, where the `vₓ`, `vₓ`, `v`,
 * etc are constants
 *
 * @example
 * ```typescript
 * evaluateImplicit2({ vₓₓ: 4, vₓᵧ: 5, vᵧᵧ: 6, vₓ: 1, vᵧ: 2, v: 3 }, 1, 1);  //=> 21
 * ```
 *
 * @param cs the polynomial to evaluate
 * @param x the `x` variable at which to evaluate
 * @param y the `y` variable at which to evaluate
