Answer: • x = -4, x = 0, x = 1Step-by-step explanation:x is a factor of all terms, so x=0 is a zero. (Eliminates choices 1 and 5.)The sum of coefficients is 0, so x=1 is a zero. (Eliminates choices 3 and 4.)Reversing the sign of the odd-degree terms gives signs of -++, so there is one sign change, hence one negative real root (by Descartes' rule of signs). This confirms choice 2 as the answer.___Of course, your graphing calculator can answer this almost as quickly.
