Question

Which algebraic expression is a trinomial? x3 + x2 – 2x3 – x2 4x3 + x2 – x6 – x +

Answer 1

x^8 - x + √6

Explanation:

The fourth expression is a trinomial (a polynomial with three terms). The term √6 is acceptable because it's a constant; it's the coefficient of x^0.

Answer 2

D.

`{x}^(6) - x + √(6)`

EXPLANATION

A trinomial is a simplified polynomial with three terms.

The first option is not a polynomial because of the presence of √x.

The second option is not a trinomial because it has only two terms.

The third option is not a polynomial because of the presence of

`(1)/(x)`

The last option:

`{x}^(6) - x + √(6)`

This is trinomial because it has three terms and cannot be simplified further.

There is not fractional exponent.
