I don't k ow if it works for negatibe one.:(


"For any polynomial function, if the sum of the coefficients and constant of f(x) is zero, then one(1) is a root. If the sum of the coefficients and constant of f(-x) is zero then negative one(-1) is a root".

Answer 1

I plugged it in and i don't think -1 works.
Right oobleck?

Answer 2
