Question

qual o polinomio que expressa a soma entre (2x+4) + 2x^2

Answer 1

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

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

Sejam os polinômios:

           $\Large\begin{cases} P(x) = 2x + 4\\Q(x) = 2x^{2}\end{cases}$

A soma dos referidos polinômios é:

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

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

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

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

✅ Portanto, a soma dos polinômios é:

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