Question

Equação do 2 grau X2 + X + 1 = 0

Answer 1

$\large\bm{ {x}^{2} + x + 1 = 0 } \\ \large\bm{\begin{cases}a = 1 \\ b = 1 \\ c = 1\end{cases}} \\\\ \large\bm{ \Delta = {1}^{2} - 4 \times 1 \times 1} \\ \large\bm{\Delta = 1 - 4 \times 1 \times 1} \\ \large\bm{\Delta = 1 - 4} \\\large\bm{\Delta = - 3}$
