What is the zero of the polynomial \(p(x)=4x+20\)?

Answer and explanation

Correct answer: -5

The zero of a polynomial is the value of \(x\) for which \(p(x)=0\). Thus, \(4x+20=0\), so \(4x=-20\) and \(x=-5\). Therefore, option B is correct. \(-4\) is merely the negative of the coefficient and is not the zero. Exam tip: Set a linear polynomial equal to zero before solving for \(x\).
