Vedclass · Answer

(A) The foci are $(\pm 4, 0)$,which lie on the $x$-axis. The standard equation of the hyperbola is $\frac{x^{2}}{a^{2}} - \frac{y^{2}}{b^{2}} = 1$.Given the foci are $(\pm c, 0)$,we have $c = 4$,so $c^{2} = 16$.The length of the latus rectum is given by $\frac{2b^{2}}{a} = 12$,which implies $b^{2} = 6a$.Using the relation $c^{2} = a^{2} + b^{2}$,we substitute $c^{2} = 16$ and $b^{2} = 6a$:$a^{2} + 6a = 16$$a^{2} + 6a - 16 = 0$$(a + 8)(a - 2) = 0$Since $a > 0$,we have $a = 2$.Then $b^{2} = 6(2) = 12$.Substituting $a^{2} = 4$ and $b^{2} = 12$ into the standard equation,we get $\frac{x^{2}}{4} - \frac{y^{2}}{12} = 1$.

Find the equation of the hyperbola satisfying the given conditions: Foci $(\pm 4, 0)$,the latus rectum is of length $12$.
