$\Large\begin{gathered} \begin{gathered}\large \overline{ \boxed{\boxed{ \begin{array}{r}\mathsf{ \Large\bm{}Formula: \\ f(x) = a {x}^2 + bx + c }\end{array}}}} \end{gathered}  \end{gathered}$

$\Large\bm{}f\left(1\right) = - 2\left(1 + 1\right) \\\Large\bm{}f\left(1\right) = - 2 + 2 \\ \Large\bm{}f\left(1\right) = 0$

$\bm\Large\begin{gathered} \begin{gathered}\large \overline{ \boxed{\boxed{ \begin{array}{r}\mathsf{\red{Bons~Estudos} }\end{array}}}} \end{gathered}  \end{gathered}$
