A practical, root-focused JavaScript polynomial utility library.

/**
 * Returns the negative of the given polynomial (p -> -p).
 * 
 * @param p 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`
 * 
 * @example
 * ```typescript
 * bNegate([1n, -2n]); //=> [-1n, 2n]
 * ```
