What is the highest power of the variable \(a\) in the polynomial \(a^2+2a+1\)?

Answer and explanation

Correct answer: 2

The powers of the variable in the terms are 2, 1, and 0. The greatest of these is 2, so the degree of the polynomial is 2. Option 1 gives the power of only the linear term \(2a\), not of the entire polynomial. In an exam, identify the highest power of the variable to find the degree.
