Answer:

 {a}^{2}  - 14a - 51  = 0\\  \\ d =  {b}^{2}  - 4ac \\  \\   = ({14}^{2}) - 4(1)( - 51)  \\  \\  = 196 + 204 \\  \\  = 400 \\  \\  \sqrt{d }  = 20 \\  \\   \frac{ - b -  \sqrt{d} }{2a} and \frac{ - b \ +  \sqrt{d}  }{2a}  \\  \\  \\  \frac{14 - 20}{2}  =   \frac{ - 6}{2}  =  - 3 \\  \\  \frac{14 + 20}{2 }  =  \frac{34}{2}  = 17
