Question

calcule o valor da soma dos polinômios( 2x+y+3 )+ ( -5x + y – 1 ).

Answer 1

Resposta:

-3x + 2y + 2

Explicação passo-a-passo:

(2x + y + 3) + (-5x + y - 1)

=

2x + y + 3 - 5x + y - 1

=

-3x + 2y + 2

Answer 2

✅ Após resolver os cálculos, concluímos que o polinômio que representa a soma dos dois polinômios dados é:

 $\Large\displaystyle\text{ \begin{gathered}\boxed{\boxed{\:\:\:\bf S(x, y) = -3x + 2y + 2\:\:\:}}\end{gathered} }$

Sejam os polinômios:

       $\Large\begin{cases} P(x, y) = 2x + y + 3\\Q(x, y) = -5x + y - 1\\S(x, y) = \:?\end{cases}$

Calculando a soma dos referidos polinômios:

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

                    $\Large\displaystyle\begin{gathered} = (2x + y + 3) + (-5x + y - 1)\end{gathered}$

                    $\Large\displaystyle\begin{gathered} = 2x + y + 3 - 5x + y - 1\end{gathered}$

                    $\Large\displaystyle\begin{gathered} = -3x + 2y + 2\end{gathered}$

✅ Portanto, a soma é:

    $\Large\displaystyle\begin{gathered} S(x, y) = -3x + 2y + 2\end{gathered}$

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