question 164

Multiple Choice

Use the quadratic formula or graphing methods to
- $$8 x ^ { 2 } < 8 x + 8$$

• A) \(x < \frac { 1 - \sqrt { 5 } } { 2 } \approx - 0.618\)
• B) \(\frac { 1 - \sqrt { 5 } } { 2 } \approx - 0.618 < x < \frac { 1 + \sqrt { 5 } } { 2 } \approx 1.618\)
• C) \(x < \frac { 1 - \sqrt { 5 } } { 2 } \approx - 0.618\) or \(x > \frac { 1 + \sqrt { 5 } } { 2 } \approx 1.618\)
• D) \(x > \frac { 1 + \sqrt { 5 } } { 2 } \approx 1.618\)
