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

ANSWERD.[tex] {x}^{6} - x + \sqrt{6} [/tex]EXPLANATIONA 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 [tex] \frac{1}{x} [/tex]The last option:[tex] {x}^{6} - x + \sqrt{6} [/tex]This is trinomial because it has three terms and cannot be simplified further.There is not fractional exponent.
