Question

Calcule a soma dos polinômios : (2x + y + 3) + (-5x + y -1)

Answer 1

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

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

= -3x + 2y + 2

Answer 2

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

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

Sejam os polinômios:

               $\Large\begin{cases} p(x) = 2x + y + 3\\q(x) = -5x + y - 1\end{cases}$

Calculando a soma dos polinômios, temos:

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

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

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

✅ Portanto, a soma dos polinômios é:

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