Use the Quadratic Formula or Graphing Methods to
- $$4 x ^ { 2 } + 20 x + 8 \geq 0$$

Use the quadratic formula or graphing methods to
- $$4 x ^ { 2 } + 20 x + 8 \geq 0$$

A) $x \geq \frac { - 5 + \sqrt { 17 } } { 2 } \approx - 0.438$
B) $\frac { - 5 - \sqrt { 17 } } { 2 } \approx - 4.562 \leq x \leq \frac { - 5 + \sqrt { 17 } } { 2 } \approx - 0.438$
C) $x \leq \frac { - 5 - \sqrt { 17 } } { 2 } \approx - 4.562$
D) $x \leq \frac { - 5 - \sqrt { 17 } } { 2 } \approx - 4.562$ or $x \geq \frac { - 5 + \sqrt { 17 } } { 2 } \approx - 0.438$
