I'm going to assume that you can get to the center, foci, vertices, and equations of the asymptotes if you have the Standard form.

My calculator said it, I believe it, that settles it

Find the Standard equation of hyperbola, center, foci, vertices at asymptotes of the function 4x² - 5y² + 32x + 30y = 1.
Thank you!
~~~~~~~~~~~~~~

4x^2 - 5y^2 + 32x + 30y = 1  ====>  Complete the squares for x- and y-terms separately  ====>  


(4x^2 + 32x) + (-5y^2 + 30y) = 1


4(x^2 + 8x) - 5*(y^2 - 6y) = 1


4*(x^2 + 8x + 16) - 5*(y^2 - 6y + 9) = 1 + 4*16 - 5*9


4*(x+4)^2 - 5*(y-3)^2 = 20.     <<<---=== Divide by 20 both sides


%28x%2B4%29%5E2%2F5 - %28y-3%29%5E2%2F4 = 1


%28x%2B4%29%5E2%2F%28sqrt%285%29%29%5E2 - %28y-3%29%5E2%2F2%5E2 = 1


It is the standard form equation for a hyperbola.


The hyperbola has the center at  (x,y) = (-4,3).


Real axis is parallel to x-axis; imaginary axis is parallel to y-axis.


Real semi-axis is sqrt%285%29 units long;  Imaginary axis is 2 units long.


Vertices are at y= 3:  x = -4+-+sqrt%285%29  and  x= -4+%2B+sqrt%285%29.


The foci are  x= -4+-+sqrt%285%2B2%5E2%29 = -4 - 3 = -7  and  x= -4+%2B+sqrt%285%2B2%5E2%29 = -4 + 3 = -1.
