Which expression is a polynomial in (x), but both (x^3) and (x) terms are absent?

Answer and explanation

Correct answer: \(x^4+5x^2-6\)

\(x^4+5x^2-6\) is a polynomial because the powers of \(x\) present are \(4, 2\), and \(0\), all of which are non-negative integers. It has no \(x^3\) or \(x\) term; a polynomial does not need to include every intermediate power. Option B contains an \(x^3\) term, option C contains an \(x\) term, and option D is not a polynomial because it has a negative exponent. Exam tip: in a polynomial, every exponent of the variable must be a non-negative integer.
