For which expression is the value at (x=0) equal to its constant term?

Answer and explanation

Correct answer: Any polynomial in x

In any polynomial in x, every term containing x has at least one factor of x. On substituting x=0, all such terms become 0, leaving only the constant term. Hence, the value of every polynomial at x=0 equals its constant term. “Only quadratic” or “only linear” is incorrect because this rule applies to polynomials of every degree. Exam tip: To find a polynomial’s constant term quickly, substitute x=0.
