I think this is what you are looking for:

∴2+2=16+2×12=40

∴

Now, (−)2=2+2−2=40+2×12=64

∴(−)=64‾‾‾√=±8

∴

Find the vertices and foci of the hyperbola with equation (x-5)^2/81 -(y-1)^2/144 = 1
vesna_86 [32]
Given the equation of an hyperbola in the form:
\frac{(x-a)^2}{b^2}- \frac{(y-c)^2}{d^2}=1
Then the focus of the hyperbola is (\pm\sqrt {b^2+d^2},0)
Compute like this:
\sqrt{81+144}=15
So the two focus points are (\pm15,0)
The vertices are given by the formula: (\pm a,0)
We deduce the two vertices of the given hyperbola: (\pm9,0)
since \sqrt{81}=9
