What is the degree of the polynomial (-25)?
Answer and explanation
Correct answer: \(0\)
\((-25)\) is a non-zero constant polynomial because it has no variable term. Every non-zero constant polynomial has degree \(0\). A polynomial of degree \(1\) must have a variable with highest power \(1\), which is absent here. Exam tip: only the zero polynomial has an undefined degree; every non-zero constant has degree \(0\).
