Question

Use synthetic division to prove that the number k is an upper bound for the real zeros of the function f.

k = 4; f(x) = 4x^4 - 16x^3 + 8x^2 + 16x - 12

Answer 1

If synthetic division is performed by dividing by x-k, where k>0, and all the signs in the bottom row of the synthetic division are non-negative, then x=k is an upper bound for the zeros of the polynomial.

Answer 2

can you do the synthetic division? or do you need help with that?

Answer 3

I need help with that.
