What is the constant term in x² − x?
Answer and explanation
Correct answer: 0
A constant term is a term that contains no variable. The expression x² − x has two visible terms: x² and −x. Both contain x, so neither is constant. When a polynomial has no separately written number-only term, its constant term is taken as 0. Therefore option C is correct. Option A is the quadratic term, and option B represents the variable term with coefficient −1; neither is a constant. Option D would be correct only if a standalone 1 were actually present, but no such term appears in the given expression.
