foci ((x+3)^2)/9-((y-2)^2)/(16)=1

foci

(2, 2), (- 8, 2)

Solution steps

(h + c, k), (h - c, k)

Calculate Hyperbola properties

\frac{( x + 3 ) ^{2}}{9} - \frac{( y - 2 ) ^{2}}{16} = 1 :

Right-left Hyperbola with

(h, k) = (- 3, 2), a = 3, b = 4

(- 3 + c, 2), (- 3 - c, 2)

Compute

c :

c = 3^{2} + 4^{2} : 5

(- 3 + 5, 2), (- 3 - 5, 2)

Refine

(2, 2), (- 8, 2)
