Which polynomial is linear and has zero (0)?
Answer and explanation
Correct answer: \(5x\)
\(5x\) is a linear polynomial because the highest power of \(x\) is 1. To find its zero, set \(5x=0\); this gives \(x=0\). Although \(x^2\) also has zero 0, it is a quadratic polynomial because its degree is 2, not linear. Exam tip: a linear polynomial always has degree 1.
