Which of the following is a zero of the polynomial \(p(x)=x+4\)?

Answer and explanation

Correct answer: −4

A number is a zero only when the value of the polynomial becomes 0. Since \(p(-4)=-4+4=0\), \(-4\) is the correct answer. Substituting \(4\) gives \(p(4)=8\), not 0. In an exam, verify a possible zero by substituting it into the polynomial and checking whether the result is 0.
