Which hyperbola has both vertices in the same quadrant?

Answer:

Given a hyperbola with an equation:

Foci will have coordinates:

F₁ (xc - c, yc) and F₂ (xc - c, yc)

where c = √(a² + b²)

While given a hyperbola with an equation:

Foci will have coordinates:

F₁ (xc , yc - c) and F₂ (xc , yc - c)

where c = √(b² + a²)

Now, start looking at the equations you are given as a solution and note the option A and C do not represent a hyperbola since they don't have both parenthesis squared.

For option B) you have:

xc = 24

yc = 1

a² = 24² = 576

b² = 7² = 49

Therefore:

c = √(576+49) = √625 = 25

and

F₁(-1 , 1)  F₂(49 , 1)

which are not on the same quadrant.

For option D) you have:

yc = 16

xc = -1

a² = 9² = 81

b² = 12² = 144

Therefore:

c = √(144+81) = √225 = 15

and

F₁(-1 , 1)  F₂(-1 , 31)

which are on the same quadrant.

Hence, the correct answer is b i think

How do I solve this
sdas [7]
\bf \textit{difference of squares}
\\ \quad \\
(a-b)(a+b) = a^2-b^2\qquad \qquad 
a^2-b^2 = (a-b)(a+b)\\\\
-------------------------------\\\\
\cfrac{2x}{x^2+2x-24}-\cfrac{x}{x^2-36}\quad 
\begin{cases}
x^2+2x-24\implies (x+6)(x-4)\\
--------------\\
x^2-36\implies x^2-6^2\\
(x-6)(x+6)
\end{cases}

\bf \cfrac{2x}{(x+6)(x-4)}-\cfrac{x}{(x-6)(x+6)}\impliedby 
\begin{array}{llll}
\textit{thus our LCD is}\\
(x-6)(x+6)(x-4)
\end{array}
\\\\\\
\cfrac{[(x-6)2x]~-~[(x-4)x]}{(x-6)(x+6)(x-4)}\implies \cfrac{2x^2-12x-x^2+4x}{(x-6)(x+6)(x-4)}
\\\\\\
\cfrac{x^2-8x}{(x-6)(x+6)(x-4)}
