Question

Qual o polinômio que expressa a soma entre -9x + 5 e + 7x - 1

Answer 1

Resposta:

-2x + 4

Explicação passo a passo:

(-9x + 5) + (7x - 1) = -9x + 7x + 5 - 1 = -2x + 4

Answer 2

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

      $\Large\displaystyle\text{ \begin{gathered}\boxed{\boxed{\:\:\:\bf S(x) = -2x + 4\:\:\:}}\end{gathered} }$

Sejam os polinômios:

           $\Large\begin{cases} P(x) = -9x + 5\\Q(x) = 7x - 1\end{cases}$

Calculando a soma dos polinômios, temos:

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

                    $\Large\displaystyle\begin{gathered} = (-9x + 5) + (7x - 1)\end{gathered}$

                    $\Large\displaystyle\begin{gathered} = -9x + 5 + 7x - 1\end{gathered}$

                    $\Large\displaystyle\begin{gathered} = -2x + 4\end{gathered}$

✅ Portanto, a soma dos polinômios  é:

         $\Large\displaystyle\begin{gathered} S(x) = -2x + 4\end{gathered}$

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