Question 217

Multiple Choice

Use the quadratic formula or graphing methods to
- 2x2+10x+402 x ^ { 2 } + 10 x + 4 \leq 0


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