 *
 * @param a a polynomial with coefficients given densely as an array of
 * bigints from highest to lowest power, e.g. `[5n,-3n,0n]`
 * represents the polynomial `5x^2 - 3x`
 * @param b another polynomial.
 *
 * @example
 * ```typescript
 * bMultiply([1n,2n,3n], [2n,5n,3n,5n]); //=> [2n, 9n, 19n, 26n, 19n, 15n]
 * ```
