question 242

Multiple Choice

Find the real zeros, if any, of each quadratic function using the quadratic formula. List the x-intercepts, if any, of the
graph of the function.
- $$\mathrm { F } ( \mathrm { x } ) = 5 \mathrm { x } ^ { 2 } - 7 \mathrm { x } - 1$$

• A) \(x = \frac { 7 + \sqrt { 69 } } { 10 }\)
• B) \(x = \frac { - 7 \pm \sqrt { 69 } } { 10 }\)
• C) \(x = \frac { 7 \pm \sqrt { 69 } } { 10 }\)
• D) No real zeros or \(\mathrm { x }\)-intercepts
