Question

Which of the following is a trinomial with a constant term? A. 4x4 + 2x2 - 2x B. -3 + 4x4 C. 2x2 - 5 + x D. 4x4 - 3x2 + x

Answer 1

C. 2x² - 5 + x is a trinomial with a constant term
That polynomial has three terms: (2x²), (-5) and (x) 
Term (-5) contains no variable, so this is a constant term.
