• C) \(\text { ellipse directrices: } x = \pm \frac { 81 \sqrt { 145 } } { 17 } ; \text { hyperbola directrices: } x = \pm \frac { 81 \sqrt { 17 } } { 145 }\)
• D) \(\text { ellipse directrices: } x = - 9 \sqrt { 17 } \text {; hyperbola directrices: } x = 9 \sqrt { 145 }\)
• E) \(\text { ellipse directrices: } x = \frac { 9 \sqrt { 17 } } { 17 } ; \text { hyperbola directrices: } x = - \frac { 81 \sqrt { 145 } } { 145 }\)
