Chapter 11: Q. 308 (page 1158)

In the following exercises,
(a) write the equation in standard form and
(b) graph.
$36 y^{2} - 16 x^{2} - 96 x + 216 y - 396 = 0$

Short Answer

Expert verified

The equation in standard form is $\frac{{(y + 3)}^{2}}{16} - \frac{{(x + 3)}^{2}}{36} = 1$ and the graph of hyperbola is

Step by step solution

Step 1. Given Information

The given equation is $36 y^{2} - 16 x^{2} - 96 x + 216 y - 396 = 0$

Part(a) Step 1. Calculation

From the given equation, it is clear that $x^{2} a n d y^{2}$ term have different sign and different coefficient. So, the equation represents a hyperbola.

Now, we will group the x and y term and make the coefficient of $x^{2} a n d y^{2}$ equal to 1 and then complete the squares and write as binomial.

role="math" localid="1645416233684" $(36 y^{2} + 216 y) - (16 x^{2} + 96 x) = 396 36 (y^{2} + 6 y) - 16 (x^{2} + 6 x) = 396 36 (y^{2} + 6 y + 9) - 16 (x^{2} + 6 x + 9) = 396 - 144 + 324 36 {(y + 3)}^{2} - 16 {(x + 3)}^{2} = 576 \frac{36 {(y + 3)}^{2} - 16 {(x + 3)}^{2}}{576} = \frac{576}{576} \frac{{(y + 3)}^{2}}{16} - \frac{{(x + 3)}^{2}}{36} = 1$

Part(b) Step 1. Calculation and Graph

As $y^{2}$ term is positive, so the transverse axis is vertical.

On comparing with standard form, we get,

$(h, k) = (- 3, - 3)$

And

$a^{2} = 16 a = \sqrt{16} a = 4 A n d b^{2} = 36 b = \sqrt{36} b = 6$

Thus, center is $(- 3, - 3) a n d a = 4, b = 6$

Next, we will find the equation of asymptote as follows,

$y = \frac{a}{b} (x - h) + k y = \frac{4}{6} (x + 3) - 3 y = \frac{2}{3} x + 2 - 3 y = \frac{2}{3} x - 1 A n d y = - \frac{a}{b} (x - h) + k y = - \frac{4}{6} (x + 3) - 3 y = - \frac{2}{3} x - 2 - 3 y = - \frac{2}{3} x - 5$

Thus, the graph of hyperbola is
