A student says that \(5x-2+\frac{3}{x}\) is a linear polynomial because the highest power of \(x\) is 1. What is the student's error?

Answer and explanation

Correct answer: In \(\frac{3}{x}=3x^{-1}\), the power of \(x\) is negative, so it is not a polynomial.

\(\frac{3}{x}\) can be written as \(3x^{-1}\). A polynomial permits only non-negative integer powers such as 0, 1, and 2, so this expression is not a polynomial. Exam tip: check every exponent before finding the degree.
