Answer
$$\Rightarrow \dfrac {x^{2}}{9}-\dfrac {y^{2}}{16}=1$$
Work Step by Step
Equation of hyperbola with a format of
$$\dfrac {x^{2}}{a^{2}}-\dfrac {y^{2}}{b^{2}}=1\left( a > 0,b > 0\right) $$
Foci are $\left( \pm c,0\right) ;c^{2}=a^{2}+b^{2}$
Vertices are $\left( \pm a,0\right) $
Given vertices $(\pm3,0)$ we find $a=3$ and given foci $(\pm5)$ we find $c=5$
$\Rightarrow c^{2}=a^{2}+b^{2}\Rightarrow 5^{2}=3^{2}+b^{2}\Rightarrow b=4$
Then the equation will be
$$\Rightarrow \dfrac {x^{2}}{9}-\dfrac {y^{2}}{16}=1$$
