Why would 3x + 11 + 2x NOT be a trinomial?

Answer 1

Explanation:

Because it actually simplifies into a binomial 5x+11 by collecting like terms

Answer 2

`\huge \boxed{\mathfrak{Answer} \downarrow}`

`\huge \sf \: 3x + 11 + 2x`

The above expression will not become a trinomial because 3x + 11 + 2x will get simplified to -> 5x + 11 l, which is a binomial (an expression having 2 terms). To make it simpler, trinomials are formed if there are 2 or more variables or if the given variable is squared or cubed so that the expression cannot be easily simplified.

Explanation in numbers :-

`\sf \: 3x + 11 + 2x \\ = \sf \: 3x + 2x + 11 \\ = \sf \: 5x + 11 \\ \bcancel = \bf \: a \: trinomial; \: it \: is \: a \: binomial`
