Question

qual o polinomio que expressa a soma entre 15x2 - 6x + 8x e - 5?​

Answer 1

15x2-6x+8xe-5

30-6x+8ex-5=

25-6x+8xe

Answer 2

✅ Após resolver os cálculos, concluímos que a soma dos referidos polinômios é:

     $\Large\displaystyle\text{ \begin{gathered}\boxed{\boxed{\:\:\:\bf S(x) = 15x^{2} + 2x - 5\:\:\:}}\end{gathered} }$

Sejam os polinômios:

        $\Large\begin{cases} P(x) = 15x^{2} - 6x + 8x\\Q(x) = -5\end{cases}$

A soma dos referidos polinômios é:

          $\Large\displaystyle\begin{gathered} S(x) = P(x) + Q(x)\end{gathered}$

                      $\Large\displaystyle\begin{gathered} = 15x^{2} - 6x + 8x + (-5)\end{gathered}$

                      $\Large\displaystyle\begin{gathered} = 15x^{2} + 2x - 5\end{gathered}$

✅ Portanto, a soma dos polinômios é:

          $\Large\displaystyle\begin{gathered} S(x) = 15x^{2} + 2x - 5\end{gathered}$

$\LARGE\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{\:\:\:Bons \:estudos!!\:\:\:Boa\: sorte!!\:\:\:}}}\end{gathered} }$
