Question

Select all the correct answers.Which statements are true about the result of simplifying this polynomial?t3 (8 + 9t) – (t2 + 4)(+2 – 3t)The simplified expression has four terms.The simplified expression has a constant term.The simplified expression is cubic.The simplified expression is a polynomial.The simplified expression is a trinomial.

Answer 1

$\begin{gathered} t^3(8+9t)-(t^2+4)(2-3t) \\ 8t^3+9t^4-(2t^2-3t^3+8-12t) \\ 8t^3+9t^4-2t^2+3t^3-8+12t \\ 9t^4+11t^3-2t^2+12t-8 \end{gathered}$

The true statement(s) is/are;

(1) The simplified expression has a constant term

(2) The simplified expression is a polynomial
