Which polynomial is a quadratic polynomial?
Answer and explanation
Correct answer: \(x^2-4x+1\)
A quadratic polynomial is a polynomial whose highest power of the variable is 2. In \(x^2-4x+1\), the highest power of \(x\) is 2, so it is quadratic. Option A is linear, option C is cubic, and option D is a constant polynomial. Exam tip: identify the degree by looking at the term with the highest exponent.
