Question

Which of the following is a trinomial with a constant term? A. 4x5 + 2x - 2x2 B. 5x2 - 4 + x C. x2 - 6 D. -3 + 4x4

Answer 1

Step 1: What is a trinomial expression?

A trinomial is an algebraic expression composed of three terms and is normally of the form

`ax^2\text{ + bx + c}`

Where c is the constant term

A constant term is a term without x

Step 2:

From the options, it only options A and B that are trinomial.

`Option\text{ B has a constant term }-4,\text{ because it is also a trinomial}`

Step 3:

Final answer

`\begin{gathered} Option\text{ B} \\ 5x^2\text{ - 4 + x} \end{gathered}`
