Question 255

Multiple Choice

Use the quadratic formula or graphing methods to
- 4x2+20x+804 x ^ { 2 } + 20 x + 8 \geq 0


A) x5+1720.438x \geq \frac { - 5 + \sqrt { 17 } } { 2 } \approx - 0.438
B) 51724.562x5+1720.438\frac { - 5 - \sqrt { 17 } } { 2 } \approx - 4.562 \leq x \leq \frac { - 5 + \sqrt { 17 } } { 2 } \approx - 0.438
C) x51724.562x \leq \frac { - 5 - \sqrt { 17 } } { 2 } \approx - 4.562
D) x51724.562x \leq \frac { - 5 - \sqrt { 17 } } { 2 } \approx - 4.562 or x5+1720.438x \geq \frac { - 5 + \sqrt { 17 } } { 2 } \approx - 0.438
