Question

Which of the following is a trinomial? A. 7+x/2B. √3x+1C. x+3D. 3x² + 4x+1

Answer 1

`D)3x^2+4x+1`

Step-by-step explanation

A trinomial is an algebraic expression that has three non-zero terms,In Algebra a term is either a single number or variable, or numbers and variables multiplied together. Terms are separated by + or − signs

so, idnetify each expression

Step 1

a)

`\begin{gathered} (7+x)/(2)\Rightarrow1\text{ term} \\ √(3x)+1\Rightarrow2\text{ term} \\ x+3\Rightarrow2\text{ tems} \\ 3x^2+4x+1\Rightarrow3\text{ terms}\Rightarrow trinomial \end{gathered}`

therefore,the answer is

`D)3x^2+4x+1`

I hope this helps you
