In which of the following polynomials is the coefficient of \(x\) zero?
Answer and explanation
Correct answer: \(3x^2-4\)
In the polynomial \(3x^2-4\), the term containing \(x\) is absent. The coefficient of an absent term is taken as \(0\), so option B is correct. In option C, the coefficient of \(x\) is \(1\), not zero. Exam tip: treat every missing term in a polynomial as having coefficient zero.
