I was wondering about this question:



$$ 9 x ^ 2 -4y^2-72x=0 $$



What is the step-by-step process of writing such an equation which, in this case, has the graph of a hyperbola in standard form?



Please excuse me for my messy equation. As I am relatively new to Mathematics Stack Exchange, I do not know how to insert superscripts.



Thank you ahead of time!

Note that $dfrac{(x-h)^2}{a^2}-dfrac{(y-k)^2}{b^2}=1$ is the standard form of hyperbola.



$$9x^2-4y^2-72x=0$$
$$9(x^2-8x)-4y^2=0$$
$$(x^2-8x)-dfrac49y^2=0$$
$$dfrac14(x^2-8x)-dfrac19y^2=0$$
$$dfrac14(x^2-8x+16)-dfrac19y^2=dfrac{1}{4}(16)$$
$$dfrac14(x-4)^2-dfrac19y^2=4$$
$$dfrac{(x-4)^2}{16}-dfrac{y^2}{36}=1$$
$$dfrac{(x-4)^2}{4^2}-dfrac{(y-0)^2}{6^2}=1mbox{ is the required Hyperbola}$$

So we have $$9(x^2-8x)-4y^2=0$$



$$9(x^2-8x+color{red}{16-16})-4y^2=0$$



$$9(x-4)^2-144-4y^2=0$$



so $$9(x-4)^2-4y^2=144;;;;/:144$$



$${(x-4)^2over 16}-{y^2over 36}=1$$

$$9(x^2-8x)-4y^2=9(x-4)^2-144-4y^2=0$$
$$iff frac{9}{144}(x-4)^2-frac{4}{144}y^2=1$$
