Find the Real Zeros, If Any, of Each Quadratic Function $$f ( x ) = 5 x ^ { 2 } - 28 x - 12$$

question 46

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.
- $$f ( x ) = 5 x ^ { 2 } - 28 x - 12$$

• A) \(x = - \frac { 2 } { 5 } , x = 6\)
• B) \(x = - \frac { 4 } { 5 } , x = 12\)
• C) \(x = - 2 , x = 6\)
• D) \(x = \frac { 2 } { 5 } , x = - 6\)
