Which is the constant term in the expression (2y^2+9y-11)?

Answer and explanation

Correct answer: (-11) / constant term

A constant term is a term whose value does not contain the variable. In a polynomial, the coefficient of the highest power is different from the constant term, and a term involving the variable is never constant. The sign belongs to the term and must be included when identifying it.

In \(2y^2+9y-11\), the term \(2y^2\) contains \(y^2\), so 2 is the quadratic coefficient. The term \(9y\) contains \(y\), so 9 is the linear coefficient. The term \(-11\) contains no variable, making it the constant term. Therefore option C is correct; writing 11 without its negative sign would be incomplete.
