Řešení nerovnice x² + 8x + 16 > 0
Řeš v ℝ nerovnice:
\( \large {x^{2}} + 8 x + 16 \gt 0 \)
\( \large K = \left( -\infty;-4 \right) \cup \left( -4;4 \right) = \mathbb{R} - \left \{ -4 \right \} \)
\( \large K = \left( -\infty;-4 \right) \cup \left( 4;\infty \right) = \mathbb{R} - \left \{ -4, 4 \right \} \)
\( \large K = \left( -\infty;-4 \right) \cup \left( -4;\infty \right) = \mathbb{R} - \left \{ -4 \right \} \)
\( \large K = \left( -\infty;4 \right) \cup \left( 4;\infty \right) = \mathbb{R} - \left \{ 4 \right \} \)
